Luxury Car Trade Site

I need a website exactly like iLuxCars.com. I will provide the design, I just need the same functionality as [login to view URL] except made in PHP. As far as I can tell this is a .NET site. And there's no way to tell what go's on on the back end, but a developer with the right proposal on what to do, will win the bid. Price is less important to me then a well functioning, easy to use website. So be sure to include examples of your past work with any bids. Thanks!
