I can't help your husband, but I might be able to help you, at least if you're going to be teaching in Wake County. I transferred my FL teaching license here when we relocated 3 years ago, and as you suspected, it was pretty easy to find a job, since the area is growing rapidly. You may already have these sites, but if not, these will get you started:
To get your NC license, or transfer an out of state license:
www.teach4nc.com
To apply for a position in Wake County:
www.wcpss.net
You can also call human resources to get more info, and there is a job fair in April. If your application is already on file, that makes it easier for a principal to hire you on the spot, although you don't have to wait for the job fair to interview. You can also contact principals before your application is complete. You'll want to get your signed/sealed letters of rec before you leave, the forms are in the online application. Otherwise you'll be mailing them back and forth, which I ended up doing.
Good luck!
