U should expect 8 - 10K US$ per Month + Fringe Benefits. U can do some research on the company over the inernet and if you struck a deal than its good.
recently I saw a post for a person who is selected as head of projects and they offer him 44,000 QAR (12 K US $). 26K as basic + 18 K as HRA excluding air tickets and medical, schooling. 1 US$ = 3.64 QAR
Hope this will help.
