Auto Ads Website

I need to have a Custom Autos website that lets people submit the custom car or truck for sale or trade. Need all sections of the website, from logo design to the database. Would need a admin section that could maintain all parts of the website. Need the website to be in ASP, MS-SQL & Javascript where needed. I will supply bidders similiar websites that work the way I need this website to work Payment will be made on a progress basis. Dont ask for money before you start the work.
