I'm a former Spanish teacher so I can answer any question you may have. First of all, here is a link with the salary information:

Second of all, you shouldn't have a problem finding a teaching job. There are usually job fairs in NC in the spring. It is honestly not necessary to attend them IMHO. Submit an application here around April or May:
https://schooljobs.dpi.state.nc.us/
Then look at district websites for Spanish vacancies. Once you find one, submit a resume and contact the principal. You have to be proactive. In any case, you shouldn't have a problem finding a Spanish teaching job. I was offered two positions this summer but then ultimately had to turn both down.

I hate that I did that but oh well. I've only taught in public schools in Charlotte and also in a district outside of Charlotte. I've never taught in a private school but I from what I hear they pay less. I'm not sure though. I may be wrong. As for insurance, the state pays for yours, but you will have to pay for your husband's insurance which is probably around $300-$400 a month for him. I think you said you were looking in the Triangle area and not in Charlotte. I'm not sure of the cost of rent there but in Charlotte rent for a 2 bedroom in a decent place is at least $1000. Your husband would probably be able to find a bilingual job but the pay will be terrible. I was looking in 2005 and the highest paying one paid $13 an hour. The others were around $10. I know hospitals here were always looking for bilingual people to help out with patients. If you come to Charlotte, UNC Charlotte has a really good education program. Like I said before, if you want to come to NC you won't have a problem finding a Spanish position. Just don't move down here until you find a position so you can live close to where you work. We don't have a union here either. Out-of-staters are always complaining about that. I have only taught in NC and I've had duty-free lunches and 90 minute planning but that's at the secondary level but some people complain about having to eat with the students. They're probably elementary teachers IDK. Oh, and here are two more websites to help you out with your job search. This one contains results from teacher working conditions surveys:
Governor Easley's Teacher Working Conditions Initiative
This one has reviews, demographics, test scores, etc.
Great Schools - Public and Private School Ratings, Reviews and Parent Community
Both of those websites have helped me tremendously.
Let me know if you have any more questions. I'm sorry I don't know any more about private schools here.
