It is quite possible to make money from amateur recordings. These can be easily made with a cell phone.
But if you want to have professional pictures, especially as a high class escort, then you should look for a reputable photographer who has a good name in the erotic scene. You can also exchange ideas with other escorts. Unfortunately there are very dubious photographers in the scene who like to be paid for in kind or who sexually harass you. It is best to avoid them, to avoid inconvenience.
