Sorry to say it but I see a Coyote and his lilbuddy in you future. It is a great idea and on the cheap, but most people can make those themselves here or know someone that can and will do it for them as a friend and for a couple beers.
Goodluck though, I'm sure someone will not have the resourses and want them, they are beefy as hell. They may not mess with since you are not a real business.
