Here's a thought, just do it.
You can launch a site pretty easily using WordPress, a Premium theme from a resource like StudioPress, and managed hosting from WPEngine. I recommend these resources, they aren't low cost options, because their product are very high quality, and they have excellent support. Then you can use Gravity Forms to create your own survey on the site. The initial investment is low, likely < $500, and you get a jump start on building traffic to the site. You also have started out on a platform, WordPress, that is very malleable, it can evolve as your knowledge increases and your needs change.
Use FaceBook, Twitter, Pinterest, word of mouth, etc., as feeder channels for the site, initially for the survey and eventually for the proposition.
The early bird got the worm because it was looking for the worm, not because it was early.
