On second thought, you need to tell us what work you're into, so we can accordingly tell you what the salary range here in Qatar is.

I can tell you roughly 30-35K at the min, is what you would look at with the lifestyle you suggested, but if you're into admin work, that is definitely NOT what you will earn here :-P
