It's going to be difficult to get customers to pay you for this service.

In formulating the pricing you describe above, have you considered the costs of marketing (to attract customers to the service) and of operating the business (servers to store the video and provide the email and web) as well as personnel and overhead costs?

What differentiates this from all of the other game testing outsourcing companies?

Those other test labs are to identify bugs, TRC issues, localization problems, and user experience issues. Feedback Kit described play testing services. Only extremely small devs, probably, would be in need of such.

Good point! But there are also game design consulting & playtest companies that provide gameplay feedback, with occasional overlap in functional testing. (PlaytestCloud seems to be a representative example.) The difference in Feedback Kit's idea seems to be the upfront flat fee. I've never used an outside game design consulting service, but those that I've come across only seem to offer quotes on request.

Edit: Just wanted to add that I would consider using a service like this, depending on the quality of the feedback, after exhausting my list of local playtesters. The upfront flat fee is an appealing feature.
