387779 Need online auction site built

I'm looking to design and create a unique penny auction site. I'm not looking for a clone of existing sites like Swoopo, but a unique, custom built site designed to my specifications. You will need to show me examples of your work using PHP, MySQL, Ajax, and integration of social networking tools including real time chat boxes, instant messaging, twitter and social bookmarking integration, etc. You will be designing three unique interface: a buyer interface, a seller interface, and an admin. The site will need authorize .net, and paypal or google checkout integration. THIS IS A "PROJECT" FOR THE BUILDING OF THIS WEBSITE ONLY NOT A "JOB LISTING".
