Sugar dating as a kinky couple?

Hi everyone! Me and my wife are a poly couple and are pretty into the bdsm lifestyle. We are hoping to find a sb who would be interested in joining that dynamic as a second sub - unicorn hunting feels unethical, but if there's a monthly payment I feel differently

We'd be looking for at home meet ups only (after a few hotel stays), and mainly a sexual kink based dynamic. Plus we are both neurodivergent and would probably only feel comfortable if the sb was too.

How would we go about finding a woman for this? I'm not super familiar with sugaring, but I know enough to suspect this is a bit niche
