I have encountered many people who have heard of KM and would be interested in taking it here. Some are Ball State students who took an Eastern martial art back home for many years and would be interested in something more practical. There is a martial arts club at Ball State. Even just a couple of workshops / demos would be well attended.
The closest school is 96th St in Indy, which is about an hour's drive away so a school in Muncie wouldn't compete with them.
