need HELP for making a dungeon to have my sub wife used lots...

I wanna do gangbangs and also let the place to couples who wanna play on their own, we think about buying a fucking machine and also need some floggers and other toys, large dildos to screw her .. any advice?
Please give us some tipps as we are pretty new to that and here in Spain some things are not so easy....
also could do photo sessions for secret spy photographers with us ourselves as models...maybe exciting to be watched from the hide...
