So most girls get free condoms? I certainly don't. Advertising for me is around £150 per month. There are also other costs.
The hourly rate may be high compared to many other jobs, but you have no idea how busy or quiet a girl is.
Last week I had 5 outcalls, two of them were booked quite a bit in advance. The nine or ten days prior I had zero.
I was speaking to poster's mention of paraphernalia on premises, the consumables. Indies will have advertising costs, agency/parlour girls may have house fees, these ancilliaries aren't extraordinary in their equivalence to civvie working costs.
An SP may choose to invest in their business by buying more expensive and extensive advertising options, outfits, lingerie, different condoms but that's an individual choice not mandatory. If it adds to the perceived value by the client then great they have some justification for the charge they make and he pays. Plenty of girls in London start with very little accoutrements and if they know how to work their punters will soon amass plenty of wardrobe and tools of the trade for free. Even if an SP paid for these that still doesn't justify the price point given how busy they could be. Popular "affordable" girls (up to 250ph) should/could be working at least several punts a day (many at least 6, more if taking hhrs and quickies), exactly how many will be by indie choice or management bookings. Once a sensible girl is making >200 per day she really should be sailing, even "cheap" girls could be this comfortable for the sake of 4 b2b/shags or <10 wanks a day. When you consider this, the economics of massage don't make sense for girls to just offer a toss unless they're in a high footfall territory like Shoreditch, Soho, London Bridge, Canary Wharf because most ordinary locations about town will offer less than 10 clients a day.
Girls who don't/can't; a) choose easily accessible incall locations; b) offer good service; c) price themselves appropriately will of course see their business suffer and probably tail off from their initial novelty value. That's as it should be for any business that doesn't plan properly. Away from the high client density (parts of) cities the business model will need to be different and depend on the demographic and transport links of the catchment area of the working location.
Rochelle, I have no idea where you are, what you look like, how much you charge, the services you offer, the affluence of the punters around you, how many punters you'd like to see a day/week, etc. What I've described above is my observations on the cheaper end of the London market; that's thousands of girls many/most of whom don't know how to work the market properly, hence our frustration and complaints and their lack of burgeoning business.
