Hello Sir,
I understand the requirement of the project and I'm well aware of classified sites like olx/quikr and their different portals. My experience in PHP ,web-designing will help you achieve the kind of project you want.
As mentioned, PHP and MySql database will be the back-end of the project, I'll be creating a personalized CMS for you which involves an admin panel for managing the content and users and a front-panel for the visitors.
Front-end will be HTML of-course with CSS and JavaScript for an interactive look to the site.
I may be new to this site (freelancer.com) but my command on the core concepts of programming and web-development and knowledge of how a project like this works will be best for the project.
I can assure you my full dedication and time to the project and an answered message anytime of the day. Rest, you can contact me for further details and we can start working on it ASAP.
Thanks.
Jappan
