My gut feeling is that you should not reduce the price at all, and instead work on proving the value you provide, just as you have identified too.
If I am working on a project that I need feedback on, and I am convinced that your solution will provide me that feedback, I'll happily pay $100. At $40, I'll be happy to take risk too. At $20, it sounds like the price is so low because the results would not be worth anything.
If the question is how to bootstrap, the best I can think of is to work closely with those 6% people and refine your product to the needed extent, proving value and getting testimonials.
I agree that $19 is too low. That page is trying to convince me that I will get ~20 comments from smart & knowledgeable people at a cost per comment of <$1.
I simply don't believe that pitch. Anyone who is willing to do that for <$1 doesn't value their time, so why would I value their opinion?
I'd increase the price, add some case study/ROI, and provide more detail about how it works (not necessarily on the landing page, but clearly linked)
