How does a "Balloon Animal" maker acquire his trade? How much money can be made?

Have you ever seen those talented people with all the twisting, and tying, to then magically create an alligator, or a dog? They get so talented that they don't even pop a balloon. Some carry markers and can paint faces on the balloons, so they look EXACTLY like a real dog. They can be entertaining for HOURS... and I'm RIVETED. You don't even have to dress like a clown to perform these magnificent feats, because the talent speaks for itself. I'm sure the money isn't that good. This seems to be one of those careers that is rewarded by the smiles of others.. what do you think? I'm making you a turtle right now, it's all I can do until I gain some more skills. Please help!
