Ideas for getting work with a non-profit or grassroots organization, and getting paid for it?

Okay, so I was walking out of work on a break and I just realized, my job is simply **not** for me! I don’t enjoy the work, the company and beyond that, I think it’s a somewhat sleazy organization. I just wrapped up a design project for a volunteer organization, and I realized with some direction and creativity I created some artwork that will be beneficial to those who see it, and it made me feel good to help out. I’d like to continue doing work like that, but I also need to make a living. I know this is a little vague, and I can expound more on the topic later, but does anyone have a clue where I should start looking? (My first step will be to enquire with the organization I helped, but beyond that, I’m at a loss.)
