We have them for our department and we got them from the Fire Marshal Safety Council in Brockville. They design several different ones. They personalize them to your department. We have purchased 8 for fire and 2 for Emergency Management.
we purchased one through a local vendor, we did the design (thankfully we have someone who is good with that) and forwarded it to them. i can send you a picture of what it looks like if you want. price was decent as well, i think it was around the 200 dollar mark
