Models and actors have come forward commenting that the "velvet mafia" (really rich reclusive gay men) have house parties to find paid companions, especially those working in the entertainment industry. The young men are invited under the ruse of "networking" but they're actually being paraded to the rich producers and the like. Some of them will be gently proposed to join other parties until eventually they start getting offers for paid companionship from these rich producers. It's never referred to as escort or rentman, but it's the very same. These are all guys that would never think about putting up a Rentmen ad or doing porn. It's hard to gauge the actual number of money they are paid as these guys are also paid in favors, vacations, material gifts,...
But there is definitely a rich echelon of gay men using their resources to get more exclusive paid companions.
