From what the others are saying, it seems it is a scam, so not worth spending any time thinking about the profile.
However, in the case that it was a genuine profile, the girl falls into the "extremely, extremely good looking" category for me, and if I was loaded I would gladly pay 300 or 400 to have someone who looks like that.
As it is, I am decidedly not loaded, so anyone over 200/hr is pretty much out of the question, no matter how good looking they are. It is a bummer to see girls you want who charge too much for your wallet, but that’s life. Either the market will bear it, the girl will drop her price down to what the market offers, or she’ll get a reality check and decide that escorting is not for her.
No girl owes it to anyone to set a certain price.
