A beautiful website with very current pictures on her blog.  
Perhaps she's flying low. I've known several ladies who are in a similar position. They aren't available for "mass consumption" as it were and prefer to play amongst a very small circle of gents. You aren't likely to know about them unless it's by referral (from another gent) or if you've stumbled upon their site online. They are often independent ladies but others have representation.
Have you found any current ads for her?
I don't know her or anything about her specifically but off the top of my head, this could be the case.
