When girls are working as a escort, they obviously get paid for their time and / or services. In general, the average salary of a escort depends on the quality, looks and on which basis she works. A escort girl can choose to work for an agency, in return get less but have everything managed, or decide to work as a independent escort, and have the management on herself. This obviously raises a bit more work such as planning, screening, marketing & more.
When girls work for an agency, the usual (legal) price is around € 50 an hour per date. Some agency's tend to offer a bit more or provide good steady (returning) clients on daily basis. 10 meetings on one night could lead to € 500 a night easily. They work hard for planning and getting the properiate clients, but also supply you with a driver and offer you security. When you work as a independent, normal or high class escort, pretty much everything is for the girl.
However costs such as advertising, photography, a website, having a personal driver and all that, over the line you are almost equal. Girls who are really beautiful, and fall within the high class escort category, obviously can charge more for their services. Agency's pay accordingly from € 100 to even € 200 an hour, legal. Independent high class girls could charge € 250 up to € 350 an hour, targetting the best clients out there. Working at a agency brings experience.
