First of all, let's clarify which escort agency we are interested in, VIP or the bottom of the market. Also, let's decide whether we are looking for an escort agency or we are looking for a job in this agency.

Advice on choosing an escort agency  (for him) .

VIP escort agency will never, I repeat, will never post information about a famous model or actress on its website.
If you suddenly see such an ad, you should know that this is 90 percent not true.
I propose to consider several options for finding an escort agency.
Option number one.
If you decide to use the services for the first time, you will of course apply for information search in  goog le .
On the Internet, there are a lot of offers from escort service agencies. Approximately 70 percent of all ads you find will be fake (with fake photos). Such sites usually hang on the first pages of the search engine. Most often these are ordinary prostitutes, who have been raised in price and pass them off as escorts.
There will be one girl in the photo, and a completely different one will arrive at the meeting. The only thing that can really be found through a search engine is forums dedicated to this topic.
It is on such forums that there is a chance to find a contact of a real escort service agency, with beautiful, real girls.
Option number two.
All more or less adequate managers of the escort service agency conduct their groups in a telegram. This is where you should look for an escort agency. I'm not trying to say that there will be fewer dummy girls, scammers and everything else in the telegram groups, no. I just want to say that it is there that you have a better chance of finding a decent escort agency. It is in the telegram groups that there are managers who work with real stars of show business, models and other famous personalities. Only there are contacts of those who will find you a beautiful young girl for business meetings, holidays and not only. The managers in the telegram have girls who have never been an escort before.

Advice when choosing an agency for work (for her) .

Working for a private escort agency gives you a much stronger sense of security than working on your own.
Use the site search, look for the contacts of the escort girls to ask and get advice.
Many agencies have offices, feel free to call or visit in person. Look at the prices and reviews for girls in this agency. Choose to call only with high escort prices.
Remember about safety, do not be discouraged when you hear that the agency will charge about 30 percent of your deal.
A good agency respects its employees and will never push for more. Indicate your scope in work when you first talk.
