103947 List items for sale site

I have a very basic PHP & MySQL website that needs an upgrade from v2.0 to v3.0. I need talented and relatively speedy programmers to work on this established website to improve the database and the database management tools. Basic project desciption involves several key aspects: 1. Customer login and listing management. The website enables listing used industrial equipment for sale. We want to give customers the ability to create an account, login, and manage their listings (change price, update pictures, change quantity available). 2. Admin login and listing management. Current Admin capabilities are very limited. Admin interface needs significant improvements. In Admin, section, we need customer management, listing management, listing category management, and email list management and distribution tool. 3. Backend development. Current database needs to be backed up and carried over to the new database. Database fields need to be added. 4. Frontend development. No design work required! Output database in current design framework. Integrate login prompts, and change navigation as required to accomodate logged in / not logged in navigation.
