A friend of mine took a polar bear a few years ago. Had a great hunt. He did this before the US import ban.
Houston, my suggestion is for you to check the Hunting Report and attend DSC or SCI shows in January. I'm sure you can get in touch with some reputable outfitters.
I am positive you cannot import it to the US, I do not know if there is any kind of prohibition for a US citizen to kill one. Might want to check with John Jackson at conservationforce.org.
