Congrats on getting in!
As far as shipping the car goes, I've received estimates ranging from $950-$1070. Some companies will ship your car and a container full of your stuff, so I'm looking into a few of those to try to simplify the process. I can pass along the names if you need (but having never used any of them before, I can't really say which one is best!).
I also feel like moving to HI is a big leap! You can't just load up a U-Haul and drive there I hope everything goes well for you and your husband during this crazy moving process
