Wow that's quite the racket. How much did you end up paying to the Domme? I don't think there is a standard practice for commercial dungeons anymore, there's so few left in the states now and every one I'm familiar with has vastly different rates and practices. NYC and Chicago are really the only places I can think of that have those types of 'houses'. There's a big difference in the commercial Dungeons that have Dommes as 'employees' VS the Dungeons that simply rent to independents or have a collective such as Atlanta Dungeon. The houses usually take a much higher cut than just having independents rent per hour.
