A friend of mine accepted a similar-sounding PIC job in that part of the world during October. Two months in-country, two weeks out.
If I remember correctly, total flight hours are not to exceed 400 during the one-year contract term.
While he's not flying the Hawker, it's an equivalent airframe, and the FO pay is 80K plus other compensation usually paid in remote regions.
You might have some room to negotiate.
