Don't know how close you are, but if willing to travel up i26 towards/to the Greenville/Spartanburg area may be able to find something. Lot of companies continuing to move into the area or expand. Also check out the
SC Works website and visit the various job websites as employers only seem to list on one or two job sites.
Also one of the tricks that can help is visit google maps, satellite view, and search for warehouses and google them/use street view to find their name if not labeled, find their website and see if they're hiring. Ya that takes a lot of time but hey it's another avenue to look.
