I haven't had much luck with looking for scholarship money outside of the school I will be attending... but the story seems to change once in 2nd year as far as outside funding sources.
There is a program through the Native American's Health program that is a full scholarship. Most of the schools have private scholarships.
Don't get too caught up on the scholarship amount unless you are getting 100% b/c a $10K scholarship at one school with higher cost of living or higher tuition may cost you more than a $2K scholarship at a school that has lower cost of living.
