I have a basic price structure for shows, that may be slightly adjusted to allow for distance and travel.
I only need 5-10 minutes to set up and start, however I usually try and attend about 20-30 minutes before I start. This is not always possible if I am traveling from one venue to another. Similar at the end, If I have another show to get to I will have to leave promptly, otherwise happy to say a slow goodbye!
I do not compare other local prices of other entertainers, if others charge more or less, that's fine by me. I do not put my prices up to match them or lower prices to unfairly compete.
