I'm lucky that I do work (daytime) for most of the big companies in the area, and know people in State and local Government.
The thoroughbred farm owners have lots of dinners and parties. They ask me to play for any of them.
I have been a long-time member of the University of Kentucky faculty/alumni club and they have entertainment for club sponsored events and suggest entertainment to members who have events there.
The restaurant I work in the summer is one of the most popular in the area. Generally, by the end of the summer season, I have 150 jobs booked for the winter.
Mostly, I'm part of the "furniture", and people call me out of habit. I also get work (graphics, research, video production, package design, etc.)for my production company from the people who hire me to play.
I've been lucky...
