Know-How Exchange : Other

I'm clueless. I need help figuring out what to "call" what I'm thinking I want to do. I'm admitting ahead of time that I'm niave and uninformed. I'm going to be entering a new field of art. I want a purpose (not just a hobby) I want to use (if I end up any good) my finished art pieces as a way to contribute to a cause (or causes) I want no profit (except maybe enough for supplies) but nearly all proceeds from sales to go to a cause. The "cause" may be a grouping of movements or diversity groups. What type of situation would this be. I realize I'm not giving too much info. I hope I've said enough. Thanks for any and all help
