Your best bet is to talk to the mamasun and tell her what you want(don't be shy they have heard it all before) then there is no grey area in the cot.
As for cost,well that varies depending on where you get the girls from,beer bars are cheaper then Gogo's by half. I would expect to pay the girls 1500 to 2000 each from a gogo plus bar fines and 1000 to 1500 from a beer bar plus bar fines.
