I personally don't have experience with doing educationnal shows about reptiles and snakes but I admire anyone who wants to do such a great thing for kids and to teach people about herps.
I would suggest teaming up with another hobbyist or two in your area to get a bigger variety of reptiles to show and more beginner species. Extra hands to help out in your presentation I'm sure would be very helpful
Plan out all the details: presentation, handling and showcasing of animals, their transport, etc. Then do a practice show with some family or neighborhood kids to get a feel of how things would go.
All that's left is to make a flyer advertizing your service. Pass it around to organizations and schools and in no time I'm sure you will be very busy going around teaching people about reptiles!
P.S. I love your snake's names! I have a Waldo too
