I would just get an evening or weekend sales job at a Mall for the money or whatever kind of job I could get quickly/easily (McDonald's/fast food even). I did that when I wanted to go to graduate school (was working full-time) and needed to save to afford that. I would not worry about whether I liked a second job or not, I'd be in it for the money/my goals and promise myself I'd only work it for 6 months or 1 year or 5 years, whatever time period you want.

Since you want to get your own place, I'd look and see if there were any apartments or rental properties that needed office bodies a couple evenings a week or weekends, etc. or if they had front desks/security, if they needed someone on the desk evenings/nights, etc. You like to take photographs, I'd see if any Realtors needed assistants to help make brochures, run errands, etc.; they are all independent contractors for their agency and have to do their own keeping track of their leads/customers and advertising, etc. Maybe you could help with that/mailings, etc. There's a lot of simple clerical work happening there. I started a whole little business with that, "Minuscule Mailings" :-) for all the independent contractors (that use UPS/FedEX as their office, etc., go hang out in one of those mailing places, get to know the owner and see if there are individuals that could use your help with administrative tasks; get enough of them and the $10-$20 here and there might add up?
