Ways to get more money?

The money from a part time job just isn't cutting it, I need every possible way to get any amount of money possible :) My goal is to make atleast one grand or so a month, more would be better. I make $700 a month with just my job, but desperately need more, The thing I am saving for is quite a hefty amount, so If you have ANY suggestions for what I could do, I'd really appreciate it (: p.s. 18th b-day coming soon, but would like ideas for the age I'm at already, thanks
