If you incorporate a local area exhibit into it you could probably get the local schools to do field trips. Like set up a mini ecosystem with local flora and fauna. That would get them there tie into the lesson plan of the school and then you could bring out the exotics at the end.

In high school we had an ecology club that did a little mini version of this and we took it to elementary schools all over central Florida. Of course we didn't make money doing it because the high school owned all the animals but it is the same type of idea.

Good Luck!
