What all do I need to make a paintball league at my local paintball place?

What all do i need to make a paintball league at my local paintball place? How many teams would i need to get to set it up? I’m talking about a league where you would play another team a few matches each week and maybe a tournament every now and then. How many people would need to be on a team for them to sign up? I would appreciate all the help!

What Fraction Of People Start Playing Paintball And End Up Shooting Someone?

I am an 11 year old boy and I want to buy a paintball gun.The only problem is that my mom says that you get practice and eventually get a real gun and shoot a person.I want to know if she is overprotective, or if she is right.Also, if anyone knows, how many people start playing paintball and end up shooting someone?
Any answer is helpful!Thank you.
