Buying Either existing cpa site or want to have one made

I am not sure what they are called but I want a site that allows you to list offers for people to complete. Its usually cpa offers or surveys which the users get pay so much to do each one and then can cash out after a certain amount.

Whether its an existing site or you would put it on my domain I would like it so I can add multiple offers, people will need to create an account to complete offers and there should be a way to track what they complete. If you have anything or can suggest were to start that would be great.

 

I have Winamazingfreestuff.com --- It needs some marketing but it's complete. I can build you a similar site if you want one. Let me know if you'd like to buy it via PM Best of luck in your search!
