My idea: Turn your challenge into a website were people can contribute and harvest ideas for free.
This is called commerce, and it doesn't have to be the cutthroat fixed sum game that corporate culture has made it.
The goal of business should be quality of life and prioritizing problem solving, not getting richer than the next guy.
So there should totally be an idea exchange!
(The [marked-for-deletion] part is a joke, by the way. It makes sense if you know the site.)
