[TheThinkTank] Liability Waivers

Looking for some examples of liability waivers for repairs and/or totally gifted bikes.

I work with a group of folks that flip bikes and do repairs for individuals in need. Unfortunately we are only able to operate at our space for a few hours at a time and usually cannot store or take bikes over night. Due to the severe disrepair of some of the bikes we come across and our limited time with them often we are not able to get them in the complete repair that we would hope.

Any co ops or collectives out there use these? What should or should not be included?

Thanks
