You might have seen some of those sketchy advertisements, similar to the "Google will Pay YOU!!! To Work From Home!" ads, which say stuff like "Get Grant Money Here!". At least, I associate those two kinds of ads as being similar.

In any case, the process of finding grants to apply for is very simple. The Department of Education grants are all on http://www.grants.gov/. Pretty much every university's Research and Evaluation Department gives out grants to the local community; check out your local Uni's website. Sometimes large corporations give out grants, sometimes individual people. In general, get in touch with the education department of your county government to find out which grants are being offered nearby and how to apply for them.

Now that I think of it, this is the main request I should have of lesswrongers. I bet anyone on this website could write a damn good proposal for any grant they come across, and I bet their project would be better than the shit I evaluate.
