I'm interested but highly doubt that the puzzle aspect of this is going to work, especially when used in competition. This is the internet, pretty much every major puzzle archetype has been posted and solved and could easily be found with google. Stock puzzles, like the one you're using as the sign-up test, can be found even easier and come with the high likelihood that the person you are asking them has already seen the puzzle before. I'd be very surprised if most of the people who have read this thread hadn't already seen the sign-up puzzle before.

I have, and I will admit it.
