[Governor of Florida in 1682]

I have a couple of offers for gigs working as a promotional clown. One for the mall twisting balloons for Back to School Tax Free Weekend. It will be inside in the middle of the halls so in AC but I have to probide the supplies. The other is for the flea market. They are providing supplies such as helium , round balloons and balloons for twisting. I'll be working under a shade tree near the road so folks will see the colors of my clown tent and uniform. I am stumped on what to ask for a fee for either of these since all my clowning has been volunteer under the local clown alley. HELP :?
