There are a LOT of bait and switch at the lower end of the market in Dubai so you need to be careful, the best site I've found is massage republic but beware there are still b&s on there. A simple rule if the burd looks too good to be true and she's around the 2000dhm per hour price then it's b&s. there are seriously hot hookers out there but they're not cheap.
If you want an internet wg I've found the following works best for me - google 'dubai escorts' and trawl through all the sites on the 1st page of results, you will see common photos of girls, these are usually real girls and their rates vary depending on the agency, I've had some good EE punts this way.. It can become tedious as there is a lot to go through but persevere with it and ignore the ones that are obviously model photos.
If you fancy a real time 'pull' a EE wg then almost all the trendy bars in jbr and the marina will have brass in them on the evenings these days. Very similar drill to the Marrakech thread in the Africa board in that if you can make eye contact then the burds will be obvious if they are brass and are easy to chat to and make arrangements for price and services. In my experience this is the cheapest way to punt in Dubai but is obviously not for everyone. This way you will get a 2-3hr session for 1000dhm or less.
Hope this is some help to you and I'm talking about EE brass in the above.
There are some agencies advertising Arab girls but in my limited experience of this they usually turn out to be Pakistani...
