I wanted to wish you the best as you move forward with your plans. Searching for all the scholarships can be time consuming but worth it in the end; contact the financial aide department at the schools to see their recommendations on where to look for scholarships as well. They can have some good recommendations. There are a lot of good suggestions above for the assistanceships that can be invaluable. Contact the departments to see what might be available. The other thing is that once you are accepted, there are school specific scholarships and grants that the financial aide department will determine you qualify for, which will help as well.

If this is what you want to do, don't let anyone stop you. You'll find a way.
