I found this thread and I guess I can help you
As you can see on my sig I also have such a website. I have about 3400 members and they get paid for 10months now
Check out Payment Proof from my site: Payment Proof
You earn money from your advertisers and you pay your users with the money you have earned
So you want to run such a business? What is your plan? Do you want to pay such a website? Do you want to do it by yourself and start by zero? Do you need someone who can build up such a business for you?
