Jill, it's somewhat confusing figuring out if you are looking for a Dom/Master in a personal or professional context. Resources for pro Dommes are seemingly more plentiful, but if you are looking to sub and get paid, there are resources out there for pro subs as well.
I enjoy being a submissive in my personal life, but when I'm working, there is no ambiguity about if I am to be compensated. As for scaring away vanilla clients, I haven't really found that to be a problem as I get booked by clients who are looking for vanilla sessions as well as those who are interested in kink.
The Art of Submission is an awesome resource for providers who are also pro subs/switches.
