I have no real experience there but I have a suggestion.
When you start printing, have a pre-tested negative all ready to go. Every long-time photographer that I have ever met speaks fondly of the magical moment when they saw their first image appear in the developing tray as if it were yesterday. Make that first print as dramatic as possible and you are bound to hook some of them.
After that you can teach them about test strips and chem mixing and the other, less sexy aspects of the darkroom.
