heres a company i use out here in california. they are strictly a caster supply. they can assemble you any kind of caster with any load range wheel and with or without brake units. they asemble them on the spot and im sure they can ship them where ever you need. i wouldnt go anywhere else except for maybe northern tool. I have a set of iron casters one a milling machine cart that are coated with a 1/4 inch layer of a high end urethane or something that can hold like 1000# each and wont develop flat spots. they also have some hightech plastic ones that hold the same and are a little cheaper. give them a call you wont be disappointed.
