Cashback / reward website - coding or consultancy required

I'm looking to find someone who has had experience of setting up / coding a cashback / reward site. I'd either like to get them to act as a consultant on a project, or actually carry out the work themselves. If you have experience and have built a cashback site please PM me - with details of the sites you have built / worked on. The rate will be negotiated when we decide the scope of the work - but I will pay generously for someone who has PROVEN EXPERIENCE and presents themselves well. If you have NO experience of cashback sites please DO NOT contact me. Thanks (I have put this project in the 250-750 bracket - this is only a place marker so I will not be looking at how much you bid)
