Really, are ya? Really?
Hah! I meant I'm surprised one of the older guys on this forum haven't descended upon this thread to crush hopes and dreams... 
Wasn't trying to be a dick (except in that last post
), but when you start charging money to play at a place, it changes a lot of rules. It's not an informal get together (like the pick up games at SASCO or Four Peaks), it becomes a business. All the laws start to apply. Licenses, insurance, and inspections will be needed.
WW6mm, if you're planning on having this move forward, you're gonna have to take care of this and play by the rules or you could be looking at fines and lawsuits if someone is injured on the property. Unless you have a lawyer draft up a waiver (and keep him on retainer), any halfway competent lawyer will shred through a homemade wavier and sue ya for all you're worth.
Permanent structures require licensing, inspection, and professional construction by competent builders. That's hard to do with donated materials and the crew of 14-18 year old kiddos you've had volunteer up til now (who I'm darn sure have little to no actual construction experience outside of a tree house or "bunkers" at Fuji). Semi-permanent structures need to pretty solid too. If one of them collapses when someone is inside, that's a pretty bad deal.
Speaking of such, insurance is gonna be out of sight. You ever wonder why Tempe Paintball is $26.50 or Vanguard is whatever insane price they are? It's not cause they're greedy and trying to screw you over (well, maybe Vanguard is). Insurance eats up a huge amount of money. You're gonna need to figure all this out if you're going to do everything kosher (i.e. a business plan). I'm not an economist or business man myself, just using a bit of common sense and common knowledge.
TL;DR: You're doing it wrong. Unless you're going to do everything by the book, you're asking for trouble. You owe it both to yourself and the people that would be playing at the field to do this the right way and safely. That's going to take money, though.Edit: completely forgot, there's also personal liability, since WW6mm owns the land. If anyone gets hurt on the land and he can be determined to be at fault, he's liable. Ain't the law grand?
