Sounds like an interesting idea, but I'd tend to go the route of finding
an amatuer who likes to share the sky. Good chance you could find
someone who'd be happy to do it for much less or nothing. One thing,
the guy with the flier is probably a good speaker who can put together
an organized "program." A lot of us enthusiastic amateurs are less
than articulate. Being able to communicate this stuff well to a group
is a real skill.
