My 2 cents-worth.
I used to have a neighbor whom was an ‘escort’. No, not anyone I had sex with, but someone I chatted with fairly often, while she lived there.
She charged US$250-300 an hour, with price breaks on multi-hour deals, was clean, had children, and generally lived like any suburban single mom. Except that her trade was her body and personality. She worked independantly, had a stable of regular customers (never called them ‘Johns’, that I can recall), went on occasional over-nighters (US$3000), always used hotels as her venue.
What she basically provided was a GFE: A Girlfriend Experience. She’d talk with them, get to know them, go to dinner or a show, and help them live a fantasy of having someone sexy being really interested in them. She also gave discretion, and would, as others have said, “Go away”. Not all of her clients were male.
In exchange, she got money, a lot of sex (most of which she said was pretty good), and had access to some of the perks of a lifestyle she’d otherwise not ever see.
According to the best info I have, most independant US escorts charge around US$250 - 400 per hour, giving price breaks on multi-hour packages, and sometimes even ‘putting it on sale’ to break open new markets, or drum up a little extra business. They also tend to give price breaks, or at least fixed prices, for regulars. Prices do go up, apparantly. It’s all about establishing that customer loyalty, while keepin the new ones coming in! Tips are not required by most independents, but they get gifts from many regulars: Champagne, flowers, lingere, jewelry, and the like. Usually quite modest, actually: US$50, or there-abouts.
Not all escorts are inexpensive, to be sure: My neighbor told me of a friend of hers that was charging US$12000 per day, two day minimum, on the DC-London-Paris circuit. Dunno if that’s true, but if so, all I can say is; I hope she left her customers in boneless ecstacy, 'cause that’s one hell of a price! She made it sound plausable, at least.
I have little or no information about agencies, and have no idea how they’re run, or what the economic routine is with them. I never got around to asking her.
Now, lest you think this is some great little world, and rush right out to join in the fun, there’s the ugly down-side: STDs, while not too common, were a constant fear. Getting abused by a new client was a fear (most escorts, as I understand, use referrals and screening proceses to establish some initial level of trust), getting arrested was a fear, and the ability to establish long-term relationships with a partner was quite difficult. Either they had to find someone whom didn’t mind (fat chance!), or they had to hide it (my neighbor’s personal choice), or find someone whom was in the business also. Yes, many are lesbian, or bi, and are simply screwing because it’s a living. Many are seriously flakey, adicted to various drugs, and have poor money-management skills, and must either finding a sugar-daddy, a regular job, or slide down the ranks into the street-walker levels as they lose their looks.
Many are in abusive relationships, and a large portion crash-n-burn before age 35.
Most, at this level, get a job or get married. Divorce is almost guaranteed, the first time they marry, as they’ve not very good at establishing long-term relationships.
Not a life many would choose, IMO.
