.... and unless you can land a contract with Halliburton/KBR, you're not looking at mighty big dosh. To be eligble for a job with KBR, you'll probably need US citizenship, unless they've become very desperate as of late.
The outfit what keeps me in beer and sandwiches is one of the few commercial operators in IQ. The money is not great, not by a longshot. The only upside is there's bugger all to spend it on whilst in country, so you can still save a bit. Work is generally speaking 6 on / 4 off (we're talking weeks here) working 12 hours + a day. Oh, and you will get shot at, either by the locals or their liberators.
Mate of mine went and did it, the silly sod. Was stood out on the ramp marshalling the aeroplane in one fine day, when 3 mortar rounds landed around 50 meters from his postion, blowing him off his feat. Few days later, and the US went to code "Red" which means don your flak jacket and seek shelter. Couple of days after that, they went code "Black" which means they suspect someone has managed to get inside the airfield. During Code Black they'll shot at anything and anyone who moves. My mate wisely sat very still in his portacabin. Few days after that (I kid you not) the portacabin next to his took a RPG round during a Code Black and was blown to very small pieces. Now my mate was in really deep doo-doo; leave the cabin and get shot at by the Americans, or stay put and risk getting blown to small pieces by a insurgent RPG. Oh, and all this was almost 2 years ago when things were much more quiet than today. I won't reveal his T&C in public, but you'd be laughing hysterically if I told you.
Sure you still want to go?

Stuff the "I'm good at what I'm doing". Everybody only goes there for the money.
