Skilled puppeteers may not be as easy to come by as clowns, magicians, or other artists. You may have to call one in from outside your local area, which may add a travel fee to the amount you're already paying for the performance. It should not, however, be exorbitant.
Most of us are familiar with marionettes and hand puppets, but we rarely think of shadow puppet theater when hiring a puppet show. These performances consist of shadows cast by puppets and cut-outs on a lighted screen, and originated in the Orient, particularly Bali.
