472030 Groupon clone

I need Groupon clone, front end and back end. Please bid only if you ALREADY HAVE BUILT Groupon clone website. The website should have the same functionality like Groupon with small modification in payment gateway and friend referral credit. For friend referral credit, I want to do it like [login to view URL] where the person will get the deal free if 3 persons she/he referred sign up. I don't mind accepting the same script you previously created but I need simple modification on logo, colours and maybe layout (I need to see your existing layout first). The site needs to be able to login via Facebook Connect, Twitter and LinkedIn interaction. Back end must be user friendly. You need to install the script in my host server. I need to own full source codes. All bugs fixes must be free of charge for 1 year. Please let me know your Demo site of your previously built Groupon clone.
