I missed the $3200 - 4000 per session.

It sounds very expensive unless it includes travel expenses.

Let's say it was standard BSDM and her 2-hour rate was $800
Airfare can vary a lot but let's say it was $1000
Lodging for 3 nights we'll use $900
Car rental or rideshare $150
Food $200
That's almost $3200 and I'm not being thrifty.
