Get a job at a car dealership or tire shop. Porter, cashier, whatever. They are desperately hiring and open 60 hours a week. Befriend a mechanic there and get an "easy sticker" and maybe even learn something new.

For living quarters, try working "night audit" at a hotel. You're the desk clerk for third shift. They might have a room for you, or, if not, at least you're off the streets for the night. Job comes with a computer, use that or your phone to find a better job. There are busy times of the night and quiet moments too. If not night audit, work housekeeping-- they are desperate in that dept too.
