gofreelance has a marketplace and I've seen some gigs go around. It all depends in what business you are in, as usual software developers like me in super high demand, so you have no issues making︀ much more than 10k AED ( the highest I got oferred was 35k a month︁ ), especially if you reside in dubai full time as companies require local substance to︂ be considered Dubai companies. Remember that Dubai still has that hideous thing where pay is︃ based on your passport, at least local companies do so, avoid them if you have︄ the wrong passports but the right skills. In general, as I wrote above, as long︅ as you pay your visa, your insurance, and spend some time in Dubai nobody is︆ ever going to bother you, in my opinion.
