OP - PM me for more info
I will say this - you cannot make in Dubai what you could make 2 years ago. 2 years ago you couldn't make what you could make 4 years ago. Many girls have given up on Dubai because rates have decreased dramatically. There are stunning russian, lebanese and Moroccan girls in the bars who will do the whole night for 400-500 GBP or less.
Qatar is boring as hell, strict and conservative. I had to chuck a guy from my hotel who was fake police, it's common. He'd done this with others to get free sex. You need to be very careful working in Qatar and cannot see very many people at all.
Bahrain is more open than Qatar.
Beirut and Istanbul are a lot more fun places to visit
In Dubai you get - arabs of all kinds (levantine and GCC arabs) north africans, east africans, greeks, western businessmen, indians, pakistanis, sometimes rich chinese, malaysian or Filipino. (There are actually a lot of pakistani and indian guys here with $$, I have some great pakistani clients) You have to have the patience of a saint and a strong ear for bullshit as there are many many many timewasters, no shows, hagglers, dodgy guys, pimps etc.
I am super super strict with guys here. I will not haggle at all. I won't see guys under 30 and I turn down 8/10 people who request a meeting
Where you are from will affect what rate you can get, a lot of the time
