Tony said I was talking to someone about preschools last night. I think I may tackle that venue. Right now they only call in the summer, but I may give them a Tuesday morning special price.
This could be a whole separate discussion, but I like daycares. They fill out the middle of my week when I have less demand. The price is around the same I charge for birthdays, but the managers are used to spending money and bringing entertainers in for special days.
I have a few days cares locally that I do 2 or 3 times a year.
Try a postcard marketing to your local daycares to test the water.
