I checked out her site. She strikes me as one that you may want to risk taking one for the team on. Try emailing her stating that you would like to see her, do not get graphic. You should be able to gather some valuable insight about her from her response to your email. Some of the information on her site indicates that she escorts on a limited basis due to other activities, the email exchange should bring this out and allow you to develop a feel for her.
As I checked her sight, I began to like several things about her, I wish that business obligations made it possible for me to give her a try, but now they do not.
Wish I could be of more help, but it looks like the lady works under the radar. My feeling though is that in her case, that is not a bad sign.

Very flexible girl.  You can get her into all kinds of wild positions.  Smart and friendly, too.  The Sultan recommends.
