I can help you with this. Do you think you'd be comfortable staying in a Hostel as opposed to a Hotel? Are you at all familiar with Airbnb?
You can get a hostel for as low as $24 a night. The tradeoff is you do not get a private room. It is a more communal approach. See the picture attached--bunk beds, for example. How would you feel about that?
I suppose you could try craigslist
