With your husband being an aircraft mechanic, he'll have some good options in Greenville. There are three area airports with operations based at each that employ a good number of mechanics:
Downtown Municipal Airport:
This used to be Greenville's main airport, and now serves corporate jets and charters. One of the nations largest air taxi services is based in Greenville and uses this airport for maintenance of their fleet. SATSAir.
Fly on your own personal aircraft at a cost you can afford

The main commercial airport. Mostly airline traffic, but a few FBO's. Stevens Aviation has a large operation at GSP.
