There are definitely opportunities in visual merchandising but as elphaba says, the pay isn't likely to be great. That, coupled with the high cost of accomodation in Dubai would probably mean you wouldn't be able to expect the same standard of living as you do in the UK. But I'll end on a positive note, if you're looking for a change and haven't got any ties/committments at home why not give it a go and see what happens! What is there to lose?
