If you're looking into hiring a magician and they don't immediately ask you about the type of audience and event, consider moving on to the next candidate. A good magician should be willing to tell you, right away, how best they can provide for your specific needs.
Think of how much fun it would be if you were to bring in a magician to the next company gathering. These people will amaze and wow almost anyone with their illusions as well as their juggling abilities in most cases. These people will do wonders to get your people motivated.
