Hmm. I can see some ways for this to work.
Awhile ago I started a project converting government voting records (both elections and congressional) into a database. Would that be interesting to you?
Here's an idea: You could also host a data bounty program, and/or start a grant program for the production of these data sets.
Still missing an answer to "what are you requirements"? How do you verify data quality, etc? What format(s)?
