Create Excel-based work time sheets/project tracking - repost

Create a fast and easy to use, Excel-based weekly work timesheet for workflow and project time tracking in our small PR/media/marketing business. We want to include a graphic front end interface incorporating our company branding/feel for staff to be presented with, with access to the backend data only for management. We can provide a full graphics/design if required. The timesheet needs to have drop down selection menus listing our clients and their various departments, allocate job numbers (abbreviated client name/yy-mm-dd/job number of the day), include selection menu for job particulars (our departments/services), a space for staff comments undertaking the role, time started, finished and accumulated time spent. We also need the capability of expanding the selection criteria at any stage, and to be able to draw information and statistics from the data input. The goal of this project is to build a capability which will allow us to accurately track time spent on jobs, understand our workflow, organise job schedules, delegate responsibilities and build a database of knowledge from which we can build our business. Columns: Date – (drop down menu, date selection) Clients (list client names Department Job Number – automatically allocated using abbreviated client name, date (yy-mm-dd) and job number of the day Project – Project name Job Type – (drop down menu listing our Comments – room for employees to make comments on jobs Time Started – (drop down menu, clock selection) Time Finished – (drop down menu, clock selection) Total Time – accumulated total from start/finish columns We envisage this as the first of many jobs that we will undertake over coming weeks and months.
