I think many of you guys are missing the point. Both of the ladies in the priginal look amazing. The have great reviews. So the only issue is the price they ask ask for their time.
To many people, dropping a few grand is nothing. I friend of mine recently installed a fireplace in an ensuite bathroom at some dudes place that cost $30,000. Most of us can't really understand the point of doing something like that, but it might boil down to something as simple as he wanted one, and he can afford it, so he did it.
It is likely that these ladies are more "polished" than many girls simply because they need to be to sustain their businesses. And presumably they see a relatively small number of clients, which could mean they provide a better overall experience. If the OP can afford these ladies, then more power to him.
As for the ID thing, I ran it to this once many years ago in Chicago. I simply responded with "sorry, I don't have any references" and provided nothing more than my cell phone number and a "reassurance" that if she didn't like me when she arrived, she could leave. She came anyway and we had a great time. I was staying in a nice hotel which might have helped. Although I don't imagine "wealth" necessarily equates to good manners.
So to the OP, if you don't have the required credentials, tell her that and if she insists then move on.
