Create patreon profiles for each model & let them handle the cash, less costs & hassle for you as you dont need to worry about payment providers,
you create you own master patreon giving away discord server access, you just compartimentalize your models ove the voice channels
Crypto currencies like cins & tokens can be used to $tip the models
The easiest way of monetizing per model is to use a tipping bot!!!
one can even $airdrop to give users some free tokens to play with
