One of the best ways to get started is to go to one of the ranges that you will shoot your matches at and talk to the shooters at this match and talk to some of the shooters and find out which one of them might fit to help you get started in the sport, not all shooters have the temperment to teach someone, as a new shooter will not remember all the things at first and the teacher will need to have patience and go over things again with you.
We need new shooters in our sport, so if you find someone to help you and your personalities don't mix don't be afraid to change, we want you to enjoy the sport and stay shooting.
If you feel that you will want to shoot the sport and stay in it, buy good equipment to start then you won't have to spend your money twice. You will find some of your supplies at the shoots or someone that has it and will bring it to the next match.
good luck
