You could try selling a lot of your things on Craigslist. And make sure while you are earning all this extra money you spend absolutely nothing extra on anything. No Starbucks, no movies, nothing. If you are paying rent right now, see if you can find a way not to pay any rent. Move back home, move in with a sibling, couch surf, live in a campground, find an illegal garage apartment where you can live really super cheap, something.
