Putting out my shingle?

My husband and I are returning to our Minnesota roots by moving to Duluth in the next week or so. I’ve been a piano teacher for 16 years now. I’ve got friends and contacts in Duluth that keep assuring me that if I “put out my shingle” I’ll have a full studio in a snap.

What I can’t figure out is how exactly I do that. In my old neighborhood in Chicago I made a pretty flier and put it on people’s doorstep the first year I taught — after that it’s been word of mouth.

Anybody have any ideas for me?
