I want to develop on my goalkeeping skills, but I feel like 16 is a late age to try and join a team?

Does the SFA not have any programmes for people that can help them develop on football, just like they have coaching programs? Am I best just playing football with my mates and wait until I am 18+ and phone up my towns two junior teams(Irvine Meadow and Irvine Victoria)and see if I can train with them. Your help will be appreciated, thanks.
