Congratulations, looks like they know you as we do.
There is alot to think about but only you and your hubby can decide that one.
My only worry would be 'no benefits' for so long but your hubby may have great benefits.... health benefits are a must if one of you got sick. I think you could move ahead quicker than the most if you can handle stress well and that would be a real reason to take it. If you do, I remember you said you would be filling in one week and two week spans of time as needed so make sure they don't just give you money for gas but alot for upkeep and depreciation (they usually are pretty good about that, I think)
I wouldn't ask "will I get??" but how much will I get for expenses related to the use of my own car.
Good Luck in what ever decision you make.
