It's like any other business
There are smart people and there are stupid people. A good SP should be able to handle 3 calls a day, 5 days a week, 3 weeks a month, or 45 calls a month - that is doable and does not cause her any undue stress and will keep her fresh for her next john. Based on a quality girl in most Canadian Cities charging $250 and hour - do the math and you have $ 135,000 per year - this is very doable and is a minimum. They can earn as much as $216,000 per year if they move up to 4 tricks a day @ $300 - also very doable without burning out. Now - these are top girls I am talking about -but it is only a beginning. These "top" girls with little effort can be taught to walk, talk and dress. How to interact with senior executives and government people and in general become ho's to the rich and famous. Once they set their sights higher they can then become the $1000 per hour "call girl" and there are lots of these. These girls will earn $3000 a day in their home city and up to $5000 daily for travel - the numbers are huge.
The smart ones pay their taxes, take excellent care of their health and spend a shitload on clothes, makeup, hair, nails, skin etc. Their operating costs are huge. But give me a quality girl who is 25 and she will be making $600,000 annually for 10 -15 years depending on how well she cares for herself and how quickly the first millionaire falls in love with her. Remember - it is a business and there are good business people and bad ones.
