would like to see a new provider in my area, but she requires that i pay $50 to go through a screening process with discreet screening. I have not been able to find any reviews on this person either. please help

Even without knowing who you are talking about or where, I would suggest passing on anyone who charges $50 to go through screening.

Skip her.  Some of these "upscale" providers are living in another fantasy world.  That provider is looking at the financial end and probably won't deliver when it comes to what they say they offer.  There are far too many excellent providers out there to put up with that kind of crap.
