No, I would doubt very seriously if they would carry a reamer. This would reguire I machine tool type of store that would carry things like end mills, slab cutters, etc. The price of a reamer would approach the cost of getting the lock built from Chambers to begin with. If you have a friend that has a machine shop or works in a machine shop, he may be able to do it for you. Otherwise the cost of a one time job would exceed any savings you would save.
