Although Warmoth won't give out the vendor, I found someone that did identical type work and send in some artwork to get a quote on getting some made with my logo o0n them. At optimal width (a bit shorter on the max height of the letters) a minimal order qty. was going to run between $9-10 each. You get some economy of scale ordering much larger quantities, but the price Warmoth is charging for them is near what the absolute minimal cost for thousands would be. Manufacturing these type logos is a pain and you get a lot of waste/bad yield.
