Airshow Performer Paperwork?

I'm one of the organizers for our annual airshow/fly-in/pancake
breakfast/big kids toy show here in Iowa City. (If you're interested,
see it at www.BigKidsToyShow.com)

They've never had any "airshow" performers at this thing before (it's
been all static displays in the past) but we're thinking about adding
this aspect to the show. However, we're a 501(c)3 non-profit
organization, made up of all volunteers, with event proceeds to go
toward the construction of an aviation exhibit at The Iowa Children's
Museum -- so we don't want to spend a ton of money on performers.

We're not planning on charging admission to the event, so we would have
to obtain sponsors to pay for any performers -- but I think a class
airshow act (like the Red Baron Stearman Team, for example) will
increase our event attendance exponentially.

I'm wondering if any of you good people have any "canned" performer
contract agreements that you may have used at *your* airshows in the
past?

Any tips on insurance requirements? What should we provide, what
should we charge for? Any mistakes you may have made that you can
save us from repeating?

Thanks!
