On-Demand Game Testing Service. Good Idea?

From my over 10 years of game dev, I've found that the hardest part of game dev (after staying motivated) is getting useful feedback for your games. So a while back, I came up with a possible solution. I'd love to hear feedback about it.

So the idea is an "on-demand" testing service catered to games. You'd pay $29/tester, and you'd receive 30 minutes of gameplay, audio recordings of testers speaking their thoughts, and a post-game survey. Another $39 could get you a gameplay/controls/pacing review by a veteran game dev.

What do you guys think of this idea? I'd love to hear your feedback on service, things you think are missing, price, ANYTHING.

Thanks for your time!
