I put mini-splits into historic homes where there is not a way to put in ductwork due to the 100 year old construction methods. 

Is there a market for old historic homes build in the southern states?

Check the city zoning laws, check the future land use, is it in a historic neighborhood?

Historically, a medieval European craftsman first served an apprenticeship under a single master, and then passed a test and received papers from his craft guild that named him a journeyman, someone allowed to travel and work under a variety of masters to better learn his craft.
