Where can I find funding for an MSW degree?

I got into the MSW program at USC and I want to do it--it's a great school and a top 10 program, but they told me that very little in the way of scholarships exists for their students, and because I'm not independently wealthy, the $84,000 in tuition for that program is cost prohibitive. I've done online searches and seen the random scholarships out there from foundations, but I've been told by several people that getting an MSW degree funded is very difficult. I could take out loans, but $84,000 in debt, plus interest over the years, plus the cost of living in LA for the two years I'm in the program would make my life very difficult especially given that as a practicing social worker I would probably never make a lot of money. Does anyone know of any sources of grants and scholarships for MSW training that I wouldn't find on one of the regular university financial aid sites?
