UPS may be an option as they will ship most things but may have a complication on insurance - in their original packaging. That of course being ok. ;) Having seen Piccino’s original packing I don’t think they would be happy.
Parcel Farce are as good as anybody really, RM special delivery is handled entirely separately but there are size limits.
Biggest problem really is heavy items. They need heavy shipping containers. I believe there are packaging companies around but have never tried to find them,
Sheets of thickish polystyrene can be bought - intended for insulation, Cling film can be used to prevent things like drip trays bouncing around. Bits in bubble wrap the same. Thick strong cardboard boxes may be hard to find,
LOL From coversations with @DavecUK some time ago I suspect he knows how some are packed from new. In some cases they may even arrive on small pallets,
