Online jobs for teens?

Hi! I'm 15 and really need to start making money, but I working somewhere is difficult since I can't drive, and I don't have many neighbors at all. I was thinking freelance writing online would be interesting, even if it doesn't pay all that well, because I'm a very good writer and I would most likely enjoy it. Unfortunately, no one want to hire me to do anything for them when 15 other people who all have over a decade of experience apply also. Help!?
