IIRC, University of Illinois - UC has a graduate fellowship program, but I think it's extremely competitive. Otherwise, funding does not seem to be a popular thing in this field. I think the most effective 'back door' method of getting funding is finding work at a university or college that has a tuition-remission or tuition-assistance program. Not easy, and not quick, but it works. I work at an Ivy League that has a capped benefit and they reimburse my tuition every semester. The only problem is that I can only do one class at a time, but free is free I guess.
