I have an idea to create a system, where website owners could buy reviews/feedbacks of their websites. What I wonder, is how much they could actually pay for such a favor? I was thinking about the system, where owner can add its website and buy 1000 reviews, create its own poll, and users can answer to those poll. They also would visit that website. Is it possible that owners would pay 30 USD for 1000 reviews from real humans? Please share your opinion.
