doublevr normally exclusivity means 10 scenes a year or so at some rate around $3-4k/scene onwards.
$3,000 to $4,000 per scene? That's it? How do they make a living? Dancing in strip clubs? Private "performances"?
I have a friend who used to be a fairly popular performer 10 to15 years ago. I never asked her how much she made, but she seemed to do okay. And I know she didn't dance in strip clubs.
