What would your tips be for selling prints? For example if I take photos at a local basketball game, how would I go about pricing and selling the photos/prints to the players/parents. And also just selling some of my best shots, not from any events and such.

Also, I am 16, but I feel like I am pretty competent at photography, been following it/ doing it for 2 1/2 years now. And I know my camera lenses very very well. How would someone like me dive into doing commercial/paid photography? I feel I am at the level now that I'm comfortable to start doing this type of work. I do have a 60D, with a few decent lenses, 17-50, 70-200 2.8 by the way, and all the extras. So I do have good enough equipment also.
