I need someone to rewrite an existing site from ASP to PHP utilizing Mysql as the database with a few functions for users.  The site should utilize an opensource shopping cart for purchasing listings and advertising space.  I will provide the content and details on the entire site from an existing site.

-Written in PHP

-MySQL Server - Or any other stable database.

-Shopping Cart - Open source is preferable with payment options via paypal, google checkout and authorize.net.
