Caricature artists for hire

Hello! My car club is hosting a Halloween car show/ pumpkin launcher event on October 8th, we tossed around the idea of having a caricature artist stand there for the community. Don’t really have any specific themes unless you want to stick with the Halloween pumpkin patch theme. We’re hopeful in finding someone who would be ok with charging per piece rather than per hour and keep what you charge. ad will say pay by hour as it’s the only option. We’re in the kcmo area. Thank you!
