You may want to post on the Rest of the World section. Im not sure how much help you will receive though.

Has the contractor given you an idea of wages?
Does it include things such as insurance, housing, schooling (if needed etc)
I think the conversion for the US salary is 11,000 Dinar - 17,000 Dinar (you will to check that though)

The salary would be dependent on a few things.
If working out US, I would assume you would want to make more than you were at home.

Sorry I cant be more help.
