Have an Answer?
I'm not sure, because it's not my field, but I suspect demand is limited, and the kind of employment that is available are liable to be niche jobs. (With the exception being that History is a traditional stepping-stone to a law degree.)
Have you considered volunteering as a docent at a history museum? What about military re-enactments of famous battles? Even if it's not your cup of tea, it seems like it'd be a good place to meet people and make connections.
