Going back to school question - student loans, grants....?

[ShaneLvr_LA]

Im a mortgage/banking/residential appraisal professional who is wanting desperately to get out of this industry before the bottom falls completely out. I want to go back to school in something with medicine. nurse, ultrasound, paramedic... something. but i don't know where to start regarding the grants, student loans... there's so much information that i don't have and don't know where to find it. information that could make or break the deal of going back to shool. can anyone point me in the right direction? live in new orleans, la.

thanks in advance,
S
