Your profile says American in your late 40ies-50ies?

You will make more then 70K, and it will be based on nationality, education, experience etc. Here in Qatar, there is generally no ballpark figure on what someone makes. People in the same positions, equal training and experience may be making as much as $5000 per month less than their counterparts based on nationality.

Start applying, see what you are offered, come back to QL and post and perhaps QL'ers can offer some insight.
