I'd say that it's a definitely interesting concept- There could be a potential market for it since most people need a way to see what users think of the site. Depending on who those users are, they could even like it enough to market to their friends for you.

Perhaps I'm slightly biased towards design, but the first few seconds I saw the site- I felt it was like one of those promotional scam no risk money back guarantee how to make money etc etc schemes online. It might be because it's too template-like, but it doesn't reach out to me at all.

Also, I understand that there is a money back guarantee- but how do I know that 50 reviews at $450 isn't just outsourced by a copywriter in India? How do I know that I will get paid for each website and app job completed? Is there a quality standard that users must abide by to write a review? I understand that there's no real way to prove any of this, but what really helps me would be seeing testimonials, (I know, even these can be fake) or even better- give reputable companies a free trial and have them write a testimonial.

It's really a cool idea, but the above would be questions I'd ask myself the first time to your site.
