Build full coupon site (both front- and back-end)

Hi, Me and my business partner are looking to have a coupon site with membership functions website made. Both the front- and back-end. We're looking to have the design made from an existing mockup and a fully responsive [login to view URL] back-end would be a fully featured CMS. Prior experience is valued. Only serious bidders please. Upon bidding we will disclose reference sites and further details on the project. All information is confidential. We would prefer to work on milestone-model. If you believe you are the right fit, please place a bid and introduce yourself. Or if you have any questioned please contact me and I’ll do my best to answer. Looking forward to getting started!
