"Artists Beware"

I won't say 'wait.' I say be professional, savvy and UP FRONT about your age. Be professional and don't be all like 'I'm just a teeeenager!' but make it clear that people will be paying through your parents' Paypal, and try to get every piece done BEFORE the dispute period is up so customers feel comfortable. I don't know about the legalities except that you can't enter into a contract.

I started taking commissions at 14 and am now 20! Parents' Paypal is how I rolled.
