This site has some good information and links to loan providers.
It is commendable that you want to continue your education past your undergraduate work. I have seen some young adults that have graduated from medical school with at least $250,000 in debt. This a scary thought.
I would exhaust all measures to obtain grants, scholarships and even look at any work-study programs if available. You will be looking at paying a higher percentage on loans with your current debt load.
Good luck with your bright future.
