Would you rat out illegal whores and managers not in the Guild for say a suitable payment and a share of all the money the men or women involved profit the Guild. Say in game it takes over an illegal whorehouse you get a 2% share of the profits permanently plus a 10% cut when we sell the managers into indentured servitude for your help ratting them out. And a share of the whores income when they are forced to join or join the managers in servitude for ten years say 2% each for five years. In time you could be rather comfortable with the stipends alone.
