There's an alternate way to achieve this. Go to the same hotel. Talk to the admin and get a job as maid. Then, between 04:00 and 05:00 every evening, you can go there and work as a maid. An event will trigger, leading to the guy, Pavlin, taking your money. The next time you go there you'll get the option to try and get the money back from him.
After that it's pretty obvious. The first time you please him and his buddy, you get a part of your money back (all of it actually) but this acts as the start of the prostitution leading to the same jobs. Except, now you can work in the hotel both, as a maid and a whore!
