Ask HN Photographers: rent equipment from the owner (London)

I'm trying to get some feedback from hobby photographers. I'm working on a new idea allowing owners of photographic equipment to rent it out to others. You can post your equipment for rental on our website and people can rent it there directly from the owner. We would offer insurance options for expensive equipment rentals. Is there anybody here at HN who sometimes rents cameras or equipment from a rental shop? Have you ever given your camera/equipment to a friend?
