I think it would be wise to see if you can get accomodation allowance or company accomodation. At least then you know you have roof over your head should you not get any commision that month. Everything is paid in cheques in advance here (don't know if you know that) It seems from the people that I have spoken to that they are generous when estimating the commision you will get each month to get you here.
Pay as mentioned does seem very low if no place to stay is offered, you don't want to end up in Dubai in a small studio in the middle of Sharjah where you spend your life in traffic. Think M25 at rush hour.
