ABT: HELP: Getting a loan before scholarship kicks in.

From my understanding, the Army bonus is not disbursed for a few weeks after the first day of Dental School. I was really hoping to use that money to get my apartment situated in Chicago at least a few weeks before then....would I be able to get a bank loan to cover those costs and pay it back when the scholarship kicks in (I'm estimating about 5K to get furniture, first months rent, bills, etc.)? How would I go about that? Any advice would be appreciated!
