I haven't decided if it really matters to me (if it would really affect the decision to purchase a review), but one thing I was looking for on the page was the background/qualifications/experience/etc. of the reviewer(s). Again I want to emphasize that I don't even know yet if I really care. It could be a five-year-old doing the reviews and maybe I'd still purchase. In fact that could be a good option!

I like that you have actual reviews that you did at the bottom. It means that exposure of some kind is included in the price of the service, which you may want to emphasize as a free perk.

For the 20 eyes and 40 eyes option, it would especially be nice if you could guarantee that the "eyes" are from lots of different cultures, backgrounds, ages, professions, etc., and not just a circle of friends or something. Or kinda the opposite actually, that the eyes are from people in an industry/culture/segment/whatever relevant to the website being reviewed. Maybe have further options here for "eye type". :)

Anyway cool idea. I especially like that you have actual video review samples on the page.
