Yeah, fuck you for asking questions...
No, but seriously, you'll have to check agencies or indies around and pull up some rates from there. You could search on tryst.link for most indies. If you want recommendations, search those keywords at the top here and you should be able to find a few threads of popular women that fit your criteria with a little trial and error. If you pick out one or two that you like, search their names here if you want to read some reviews previous clients may have left re: those providers. Then, eventually, you have to make a choice and follow her booking procedure (on her ad or website).
