Its NOT hard to get Kodak to cut ANY current emulsion to ANY size requested(up to a point mechanically speaking), its just that it's hard to get all of the boxes needed to fulfill the order PAID FOR.
Remember, Canham cameras is a business. They/he makes a cut/markup on the price that Kodak quotes per box. It might not be much, but I'm almost sure he doesn't coordinate these things solely out of the goodness of his heart, nor should he !
But if an individual who feels comfortable collecting money from others worldwide, and doing it solely to help others out, and is willing to keep things in order, ship,etc. I'm sure the price can be a bit lower
