# FiveM Enhanced QBCore Server Development ## Fixed-Price Project — Maximum Budget: $1,300 USD ⚠️ **Important — Read Before Submitting a Proposal** ⚠️ Generic, automated and placeholder proposals will not be considered. Your bid must cover the complete agreed scope and must not exceed **$1,300 USD fixed price**. We are not offering hourly work or milestone payments. We are building a premium FiveM roleplay server for **GTA V Enhanced**, using **QBCore** and our existing **L2S-based foundation**. We already own most of the required scripts, MLOs, YMAPs, vehicles, weapons, EUP and UI assets. The developer’s responsibility is to review, clean, configure, merge, integrate and optimize these resources while custom-developing selected missing functionality. The goal is not to install many disconnected scripts. We want one immersive, stable and scalable ecosystem where inventory, housing, hotels, vehicles, businesses, jobs, police, EMS, prison, crime, NPCs, UI and world assets communicate through shared logic, clean exports, events, callbacks and metadata. ## Project Direction The server should move away from traditional menu-based roleplay and toward a more physical and interactive world. Examples include: * Visible, placeable and interactable item props * Realistic weapon storage, cases, slings and vehicle transport * Persistent vehicles with keys, damage, fuel, storage and history * Businesses requiring stock, deliveries, employees and equipment * Dealerships ordering and preparing vehicles before sale * Houses with access, security, storage and robbery risks * Criminal systems involving planning, heat, evidence and consequences * Police and EMS responding to crimes, injuries, NPC reports and investigations * NPCs, MLOs, streets and public spaces having meaningful gameplay purposes Realism must create roleplay opportunities without becoming a repetitive or frustrating simulator. ## Scope of Work The developer will be responsible for: * Reviewing and configuring the complete QBCore/L2S server * Cleaning, repairing and optimizing existing Lua, JavaScript and NUI resources * Removing unused files, duplicate systems, debug code and unnecessary loops * Rewriting weak, unstable or unreadable logic * Fixing exports, callbacks, permissions, database queries and resource dependencies * Adding strong server-side validation, logging and exploit protection * Merging related functionality into organized core resources * Standardizing all interfaces around the existing L2S UI, colors, fonts and interaction style * Developing selected missing features and integrations * Creating reusable shared logic instead of duplicating the same functionality across resources * Testing all work personally in GTA V Enhanced and FiveM Major systems include: * Inventory and physical item system * Housing and hotel systems * Police, EMS and prison systems * Vehicle system * Criminal and drug systems * Jobs and business systems * NPC and world-interaction system * Shared UI system * Staff, administration and development tools ## In-Game Creator Tools Authorized staff should be able to manage content in-game without editing multiple configuration files. Creator tools may include: * Job and Business Creator * House and Hotel Creator * Drug and Robbery Creator * Door, Elevator and Garage Creator * Shop and Crafting Creator * NPC and Interaction Creator * Mission and Contract Creator * Stash and Storage Creator * Blip and Zone Creator These tools must use the L2S UI style, proper permissions, server-side validation, database persistence and audit logging. ## Asset Integration The developer must install, organize, test and optimize supplied assets. ### MLOs and YMAPs Fix and review collisions, portals, rooms, YTYPs, lighting, missing props, LODs, duplicate assets, map conflicts, texture loss, streaming problems and client crashes. ### EUP Organize clothing packs, fix drawable and texture conflicts, remove broken or duplicate assets, configure job and rank access, integrate wardrobes and test male and female compatibility. ### Vehicles Configure metadata, categories, dealerships, garages, keys, fuel, handling, liveries, extras, collisions, persistence, textures and model optimization. ### Weapons Configure metadata, ammunition, attachments, animations, inventory, evidence, physical storage, first-person and third-person models, textures and conflicts. All supplied scripts and assets must be reviewed for **GTA V Enhanced compatibility**. ## Quality and Acceptance Requirements All systems must include: * Clean and readable code * Strong server-side validation * Low client and server overhead * Proper permissions and logging * No duplication exploits * Database-safe persistence * Consistent UI * Clean exports and events * Stable resource restarts * Scalable and reusable architecture Acceptance requires: * No persistent server-console or F8 errors * No unexplained warnings * No broken dependencies * No reproducible duplication exploits * No major texture or streaming issues * No crashes caused by the delivered work * Smooth in-game operation * Clean and organized source files The preferred idle performance target is **well below 0.4 ms per script**, where technically reasonable. ## Developer Requirements You must have: * GTA V Enhanced and FiveM installed * Strong QBCore and Lua experience * Experience with NUI, HTML, CSS and JavaScript * Experience with MLOs, YMAPs, EUP, vehicles and weapons * CodeWalker and OpenIV * The ability to test everything personally in-game * Reliable communication and availability for regular progress calls AI may be used as a development assistant, but relying entirely on untested AI-generated code is not acceptable.

Hi, You're building a single immersive FiveM world using QBCore, merging assets into a coherent ecosystem. Operational reality includes ongoing testing in GTA V Enhanced, with careful rollout and live adjustments. I've done similar QBCore integrations and asset merges, focusing on clean exports, validation, and minimal downtime. I'd start by validating the current flow, isolate unstable parts, then build against real usage patterns and user behavior. Sustaining data persistence across many assets without introducing race conditions. What is the preferred workflow for asset conflicts during the merge, who owns resolution and rollout timing? How should persistent assets (vehicles, houses, inventories) be versioned and tested before a live rollout? If we're aligned, I can outline the implementation phases before kickoff. Best regards, Brandon

Hi I can take ownership of the full QBCore/L2S integration and turn the existing FiveM resources into one stable, consistent GTA V Enhanced ecosystem. My experience covers QBCore, Lua, JavaScript, NUI, MySQL, exports/events/callbacks, MLO/YMAP integration, EUP, vehicles, weapons, and server-side exploit protection. The main technical risk is fragmented scripts creating duplicate logic, resource conflicts, persistence bugs, exploitable events, and unnecessary client/server overhead. I will solve this by auditing dependencies, consolidating shared logic, validating every sensitive action server-side, standardizing metadata/events, and removing redundant loops and resources. I can integrate inventory, housing, vehicles, police/EMS, crime, businesses, NPC interactions, creator tools, and L2S-styled UI around reusable core services. I will also review supplied MLOs, EUP, vehicles, weapons, collisions, streaming assets, databases, permissions, and restart behavior for GTA V Enhanced compatibility. The completed server will emphasize clean code, database-safe persistence, audit logging, consistent interfaces, optimized resource usage, and reliable in-game testing. Thanks, Hercules
