To be honest there are so few flying schools in the UAE I would be amazed if you could find a job. Plus I believe it is a different syllabus to the UK (I could be wrong but I know you cannot fly here without converting a UK PPL).
The cost of living out here is also terrifying (London prices). Maybe try posting in the Middle East forum but unless you know of a specific school (and there are only 1 or 2 in the whole country) that will offer you a job I think you are barking up the wrong tree.
Also remember that summer start here in a couple of months and it is pretty much impossible to fly GA from May till end September because it is c50 degrees C. Although it cools down to a pleasent 40 degrees C at night.
Feel free to PM me if you want any more details.
