I am in no way experienced to give you a comment, coz i am not married and i dont work in your line of work.

But from a laymans point of view, i think the deal really is ok. But you can do two things...

a) Wait for others to respond.
b) type in the words salary or something similar on the search box on the left oif this page and hit enter. Chances are you will find everything you need and more there.

All the best, man. Have a good time in Doha.
