Hiya honey!
Good to have you here
Incall locations can be expensive. A lot of girls use serviced apartments which will cost you about the same as a decent hotel but has the benefit of being a bit more homely, and lacking the prying receptionists eyes. If you can group all your incall appointments together into one or two days per week, then it can work out well for you and as business grows you can take on more days. Serviced apartments are popular because they do all the cleaning and laundry for you... and if you get on well with the maid (ie... tip her) you can get extra towels and sheets!
Some girls will rent out rooms for you to work from, but you need to be careful doing this because two girls working from the same premises constitutes this archaic country's definition of a "brothel" for which you can end up on the sticky side of the law.
Other girls don't have an incall location at all, but instead "tour". I've never tried touring myself, but I am lead to believe that it is quite lucrative... and it means you get to travel around the country too! Girls often tour in pairs so they can act as each others safety buddie.
You can use parlours for your "incall" location, but you will have to conform to the parlours regimes and give them 40, 50 or even 60 percent of your earnings... it varies from place to place and you will probably have to be able to at least offer some kind of rudimentary massage!
The most cost efficient way of doing it is to rent a studio apartment. Get a newly refitted on in a nice location rather than going cheap. Depending where you are working, it could cost very little to do that. Say it was £400 for the studio, plus £100 council tax and £100 bills.... that's £20 per day. Very efficient, so long as you can fill your days! But there are set up costs... unless you get a fully furnished place. And you can live there, or carry on living at home and enjoying home cooked dinners and free laundry! haha!
Hope this helps, and good luck.
