Although i agree with these guys on it being bloody hard work. If you can pull off a successful team out of friends that have never played paintball, when you get that first trophy its all worth it.
Best bet if to get as many people as you can you go with you on a rec day, then see if the bug catches anyone then explain the costs and commitment of tourny ball. Try and marshall at a local site too, that way you get to see any potential players and possibly secure sponsership as a 'Site Team'
Good luck man
