Did a little checking. The providers you have seen don't have great reviews. (Admitting I didn't look at everyone of their profiles). If your saying the reviews aren't detailed enough or accurate I'm shaking my head. I wouldn't have seen some of those providers based on what Was (capital W for emphasis) there.
Most of them don't have web sites.
I'm going to recommend you see ladies that aren't just Back Page and actually have good reviews. You can find good providers on Back Page but it takes research. Not just that they have reviews but that they have good ones.
