Hi runninfiend.....The Linn area does offer jobs. Three Rivers electric is headquartered in Linn. Also the Linn Technical College. Many small businesses also. Hermann has become a very touristy town over the years. Many mom & pop stores, restaurants, antique stores and such. There are a few manufacturing businesses in Hermann also. And of course the wineries!
As far as commuting, yes, many do commute to Jeff City from these areas. Good luck to you and your endeavors.
