do you have a car?? if so, around here they do what are called title loans, where places will lend you money using your car title as collateral.. i'm sure they rob you with interest rates and fee's and all of that lovely stuff, but if you're in a real jam and have a semi decent car that you own outright, then i'm sure you could get at least the needed cash by a title loan..
i'm not so sure on how they work, meaning how long that you have to pay them back, interest rates, or anything like that, but i'm sure it's not hard to look into and find the info that you'd need..
