I have a friend that does this, he does about 4 tricks and then repete. Don't know how much he makes as I hav talked to him in years as he is busy all year round with other shows. Another magician friend of mine that he knows saw him this year somewhere in Illionis, I don't know off hand what Haunted House he was working for. Hope this helped a little.
Thank you very much. If you ever have the time, do you think you could ask your friend about how much he makes, what he does, where he works, etc?
Or even better, if I could get in contact with him for a really quick 3 minute chat that would be awesome.
and I am also in Illinois. So maybe that can help
