Here's my advice..have your husband network with a national recruiter in the area where you live, if he already does not have one. Have this recruiter call their counterpart in Charlotte. That way, you are already in with the recruiter. He is a senior level person...this should not be too hard.
Second, keep your search FOCUSED on your industry...not Monster, not Careerbuilder, not any of that...
Google "Health Insurance Careers". I just did right now and came across this website:
HEALTH INSURANCE JOBS - health insurance employment health jobs employment jobs health care jobs careers resumes healthcare job postings
I know I have another website saved in my favorites at home where I actually signed up to get alerts. The positions are all senior level (probably over my head on some as they are asking for PhD's, PharmD, MPH, etc.) but they are not all in Charlotte. I'm thinking you are not dead set on the Carolinas, but if you are, this might not be good as they are all over the country (Chicago, Seattle, Florida, etc.)
He first needs to go straight to the consulting company websites that are doing managed care consulting...Premier, Amerisourcebergen, Cardinal Health, etc. etc....for this Google "Health Care Consulting Charlotte"...
