I would get an account on Planet Romeo and look for Hunqz ( or whatever they call it). I have had mine for 10 years. It includes a little bit about me and a few pictures. I have found that European escorts like seeing a picture.
You might also try a major German city, esp. Berlin. Or Warsaw. I hire a lot in Germany, but have always been hesitant with Czech's and have had bad experiences with other Eastern Europeans. They are very interested in money, book as many a day as possible, and underperform. In general I prefer to pick escorts who live where they work rather than those who move around from city to city.
