Clean and Elegant Coupon codes and deals website.

I am looking for someone to build the best coupon website in .PHP that can outpace or look better than the following three: [login to view URL], [login to view URL], rollback.com. I will be willing to offer a bonus on top of the project fees if the final product is outstanding. My name is [login to view URL] and main objective is to be listed close to the top for people to search: [Company name] + coupon keywords. For example, "bestbuy coupon", "dell coupon" in Google. The frontend should look stunning and web 2.0 look and feel and we can discuss the details in terms of functionalities. Basically, it will contain all the main functions like those three sites I mentioned above. The sites also should integrate all the social networks such as Facebook and Twitter. Also, for the next phase should be able to create an iPhone or iPad application for this coupon site. Take a look at this framework called: Sencha ([login to view URL]) I like to build on this framework if possible and take advantage of HTML 5. The backend should have an administration or backoffice that can approve, edit, add, delete new coupons. The coupons are from datafeeds (ie. .xls or excel files) and also manual entry. In other words the coupon administrator can approve quickly for new coupons or he/she can manually type in coupons. The project timeframe is one month and I will pay top dollar for the right candidate. More details will be discussed.
