Bitcoin Exchange Website Service - open to bidding

Hi there, We are looking for a creation of a website, similiar like www.btcpromo.net. We found your name in a solicition you made for another bitcoin exchange website. Furthermore to this exchange possibility of Paypal, like this sample website has, we also would like to implement exchange possiblities for Paysafecard, Ukash and CashU. All of these 3 last named exchange possibilities have a digital number code, which needs also be implemented when an exchange service is requested and send to us. This is mainly the frame work of the design of the website. Can you help us in this matter, and how much would you charge for this website and how long it takes. Payment will be in bitcoins. Looking forward to hear from you soon. Best regards. Thomas
