Obviously you'll find you need a minimum x number of members to make the monthlies, AND that number will have to be constant. It's worth a try but you have to make sure you have an exit strategy and don't get left with the bills.
It's really high risk on it's own, and then you have upkeep. I think if the big bills don't kill you, you might find the small stuff piling up. Like how clean will it be kept and will it start to look like cr@p in a few months. What if half the members want to smoke - that is a very strong possibility. Then you end up with half the membership getting po'd at the other and quitting, and as you know pool players get po'd real quickly real easily. Will everyone accept authority, or will the members all think they have equality so screw what anyone thinks. There's attrition. There's no way you keep membership up unless you get absolute loyal patrons of the game. Obviously, the big problem is the balancing act with the members.
