I own a patch manufacturing company. See www.qemblem.com
I normally would not say such a thing on this site but it seems like some guys are interested and this is something I can actually help with.
Our normal minimum is 25 pieces but since I am the owner I can do whatever I want in this regard. However, low quantities can get a bit pricey so "one offs" are sometimes more than one people want to spend.
However, if this is something you are interested in reach out to me...I can absolutely help you.
