I'm 14 and have around .3 BTC which I go from the /r/Jobs4Bitcoins. If you have programming skills that is a good option. I might be willing to pay you if you can do something useful for me. What skills do you have? If you mind sharing, why do you need the money? PM if you want some help getting established in the Bitcoin world. If you have fiat currency (fake money that every insists on using =P) you could also try LocalBitcoins.
