You're on the right site. Just need to put in the effort on getting age verified. Scroll down the forum until you can find the board for age verification, locate a local verifier and set up a meeting between the two of you.
Once your account is verified, you'll be given the option to buy online new from retailers, and used from other players.
As for starter gun? Beleive me, get an AEG, An assault rifle. Starting out with a GBB pistol or something along those lines won't really do you much good. AEG's are the staple of airsoft, and I don't really see why you wouldn't want one.
Good luck! Airsoft is a great sport and a whole ton of fun.
