I spoke to my former landlords earlier - they are receptive to the idea of having up to a 40ft container on-site for 4 weeks (price TBA), which should be plenty of time to load it once the actual inventory is finalised.
There's also an excellent welder on-site who would be able to weld stay bars into the container if required, or hold-down hoops for strapping, etc. There's a fork-lift on-site which, but I don't think it'll fit in the container (the mast is too high), however, I have a pallet truck which could be used to navigate palleted engines into place. I think I can find a source of free pallets too, if someone can clarify the wood fumigation requirements.
Is the crating idea dead in the water now, or do you want me to try to find a crating company still?
