Need $800 to move into new place

Never done this before, but I'm in a really tight spot & I figured I might as well throw a Hail Mary.

So I've been living in a house that has steadily gone downhill for about half-a-year now (meth-head roommate/s, thievery, ridiculous construction, etc), and me and one of my roommates decided to move out. We've been looking for a place for a couple of months, and ended up finding - and seeing - a place yesterday. In the meantime, I'm waiting for my tax return to come in. Now I basically have until TOMORROW by 11 AM PST to come up with the money to nail the place down, and I'm running seriously low on options. Trust that if you help me out with this, I ABSOLUTELY have you with my tax return. Fingers crossed...
