Database Website for Classified Car/motorbike/other Based Site - 2

Hi, I would like to create a website similar to [login to view URL] but aimed at damaged vehicles. The site must be simple and easy to use design with an original logo. It must also have a section for spare parts. The site will have the option to list Vehicles, Motorbikes and "Other". Then the spare parts will hvae the ability to list under of the same categories then into various sub categories based on their selection of vehicle, motorbike, other, etc. I have attached a word document which outlines the scope of the project. The payment system must be created into the system from now, but will activate at a later date once the site becomes busy. Thanks, Shane Would also like to add the following categories: Trucks , Machinery , Marine. So the top bar will be able to select between: Vehicles : Bikes : Trucks : Machinery : Marine : Then into their various sub categories.
