I was considering finding an online music service that might be willing to pay me for what I'm good at, but I reconsidered when I found that H&H Music Store was impressed with everything that I knew, and I'm only 15! If you know the ins and outs of the instruments, there is a chance that a local music store will hire you (you're a year older than I, which also helps just a little!).
I know you're not looking for money, but it does help pay for saturday courses or summer programs!
