Looking for Funding Sources for Grad School

[Politiko]

I didn't see a thread that I could hijack, so here goes:

I've applied to several universities around the country for a Masters' program in International Relations. So far, I've received acceptance from one of my 4 schools, along with a fellowship worth about 1/4th the cost. I've completed my FAFSA and I'm waiting to see what I'm offered by the feds. But it sounds like $20,000-$25,000 is the cap for federal loans per year. This leaves me with maybe $15,000 left to pull together, per year. VocRehab is probably not an option either, as 3 of the 4 schools are out-of-state.

Is there a centralized place to look at disability-based funding or another venue of funding that I've not considered yet? Do any of the big funds allot money to continuing education?

Thanks in advance.
