Getting one started is the trick. Best way to go is to pick a slow time for the bowling alley and see if you can get a break on lineage. Make the league fee something fairly large (20-25 dollars a night). You'll draw people with money. You can disguise the lineage break by saying that the center is adding money to the prize fund, that will attract more attention. Do a 30 point system with an eliminator and match play, that way people can still make a fair amount of money even if their team isn't at the top of the league. Do brackets and side pots, that way the big boys can get their competition and money fix, and the people who don't want to mess with all that can still just bowl the league. Do anything you can to find sponsors, even somebody that will give you 500 bucks for hanging their banner or putting a card on the sweep is a good start. The more added money you can advertise the better. Yeah it's a lot of work, but you can build something that makes people say, "even if you finish last in the league you still make twice as much as you would winning another regular league." Like I said, money draws people.
