Dale,
Slightly off Company...but what about a 180hp early model Maule - they have pretty much what you are looking for here in a "modified" 150...same could be said for a 160hp Pacer
There are a few listed on Barnstormers right now that seem reasonable in the way of price and fitout - for example

I know, I know, they're not a Cessna's, but they are built for the sort of stuff your talking about, and with the general spec's you've mentioned.....
Cheers
