Running an escort agency is really not that hard. Especially if you run it legally. It is much more difficult to run a dodgy business. If you are going to run an illegal business you need to keep at least two sets of books. You need to like and have complicated fake IDs to set up bank accounts and credit card merchant accounts. If you are going to be a people trafficker you spend your life lying your arse off to persuade girls to come to your country for “modelling” or “beautician” or whatever other kind of jobs. Then you need security staff – heavies – to keep them in line and prevent them from running off or telling the authorities. You probably need matching muscle in their home countries to threaten their families. And you need to be able to launder the money through front businesses or dodgy bank accounts so that you can have it in the banking system and be able to transfer it around. And that is before you advertise, promote and otherwise market to bring in clients. Which is the same for you as if it for legitimate businesses.
On the other hand, if you run a legitimate escort agency, life is so much easier. You can start real limited companies with real Directors. You can open real bank accounts with real Ids and no need for obfuscation or lying. You can build your escort agency website to showcase your Geneva escorts and keep everything simple. You can get copies of identity documents from the escort girls so that you know they are of legal age and able to work in the country legally. You can just keep the one set of books and pay taxes like any other law abiding citizen and business person.
There is no need for muscle. No need for law breaking of any kind. You still have to market, advertise and promote your services, but you would have to do that whether you operate your business legally or illegally. Your cost of recruitment is zero, because once your website ranks well on the search engines, then escort girls will just find you. Life gets really easy and simple. Why do things the hard way when you can do them the simple way?
