I've been asked to do a live origami demonstration during an event that will last approx 2 hours.
I plan on doing an array of either traditional models and my own simpler designs. My question is: How do you calculate how much you would charge for this type of scenario? I'm not asking people to give me their fees but rather some idea of how to come up with a number. I am thinking about the time involved in travel, setting up as well as the cost of any special paper I may want to use. I am a web developer by trade and charge by the hour but in this case, with the aspect of artistry added in I am not sure what is an acceptable rate. I am in the U.S. if that matters. Any info you can provide would be appreciated. Thank you, -mshannon
