Convert .ASP website to PHP and implement Shopping Cart

This project requires the site to be converted from an .asp site which uses an access database to pull information and images to show it's product to a completely PHP site with a shopping cart with some new features in addition to existing ones. The design of the website will remain the same with only small changes based on the revisions to the shopping cart. The page must also receive some search engine optimization with key words / meta tags for better search results, etc.
