Thanks Tony! I'll look around and see what others are charging in my state and I'll also look for the thread on performer's insurance. I've had a seller's permit for businesses in the past so I'm familiar with that. I shouldn't need that just for my show though, right? I also give a historical walking tour and I know that is not a taxable service; so, I don't think my shows would be either, but I may need one if I ever sell any products in the future.
I'm not sure what the atmosphere is like in Wisconsin, but I have four family members who are elementary school teachers; so, I'm hoping they can get me into their schools.
