Shit load of money in it, even when the economy is down (you do the math....blackmarket economy is recession proof )
If there is a local factory near by, offer check cashing for a small fee and a small purchace.
Sell anything Shiney...
I have a friend that started a car audio business at his dad's pawn shop 10 years ago...dude is loaded now, especially considering the 24" wheel craze...and, custum audio/video
I would try to find a place on MLK Blvd. if possible, remember: Location, location, location.
All said, I frequent pawn shops because I occasionally find good deals. You need people that know values on a broad range of things. last year I scored a new DeWalt drill w/ 2 batteries for $40. Beside it sat a old Ryobi, slightly worn, for the same price...
You will need staff that knows jewelry, firearms, weapons, musical instruments, electronics and tools.
Good luck....this is all I can come up with....
