Caricature or cartoon artist

Instead of handing out favors at our wedding we would love to hire an artist to draw a little cartoon of our guests. Something quick and sweet that our guests can take home. We might also set up a live stream of the cartoonists book/device/paper so guests can see the process on the screen in the venue. We don't mind of its a physical scetch or digitally done on a device thst we can send them later on.
