Hi Svenn
Mac's is probably the easiest source, I've used them.
I have another source that use to have a minimum order of about 100 per size, I'll try and find the name off the boxes, ordered from them years ago.
More recently though I found the outfit that I think is actually making them for everybody else but their minimum order is depending on size 250-2000.
