I wasn't quite sure where to post this, but it derives from legal proceedings so I'm posting it in Legal Corner. I don't think I can post the LINK to the actual NYT article because it contains the names of both litigants and witnesses. So you'll have to do your own search for more info.

TER posters are always speculating about how much Providers earn or might earn using their own estimates and logic. "X hours per week, 3 weeks per month, 10 months per year ... $Y per hour ..." = $Z per year

"Sex-Cult Leader’s ‘Trusted Lieutenant’ Pleads Guilty to Conspiracy."

Briefly, it appears that a college student's father cultivated a group of her classmates to have sex with him and with others as paid prostitutes. They were then forced to turn over their earnings to him. This is just one example, from the NYT article:  
"Ms. Xxxxx eventually worked as a prostitute at Mr. Yyyyy’s suggestion, she testified, turning over to him perhaps $2.5 million in earnings over about four years. ..."
.
$2.5M / 4 = ~$625,000 per year, exclusive of whatever amount she kept for herself.  I'll estimate her gross at at least $850,000 per year, before "expenses."
