Can anyone suggest a book (preferably) or video that talks about the business side of ballooing? What to charge, how to charge for different venues, etc. I have had a hard time finding anything on this specific topic.

What I am looking for is just doing balloon twisting alone with no add on services (ex. magic). I know how to base my magic shows but am lost on this aspect.

I had a lecture on restaurant ballooning called "you want fries with that?" PM me and I could share the highlights. I also have the 2 lectures I did on video, I may release it as product soon.

I would ask what type of ballooning. There are a lot ways to make money with balloons, but none of my favorite books on making money are specific to balloons. There are several great books on busking, but most of them aren't balloon specific. There are great books on doing children's birthday parties, again for clowns and magicians.

"Professional Portfolio for balloon Artists" by Bruce Kalver
"Life on the living room circuit" Tom Meyers
"Art of Krowd Keeping" Gazzo
"Strong Magic" Darwin Ortiz (Magic, but one of my favorite books about presentation)

Thanks to both of you. I have read "Strong Magic" (excellent as stated many times) and I will look into those others.
