We also used Blouin. They do a very nice job, they have the standard language for certain notices and they match your bank's colors. The signs are easy to replace when something changes.
I am "it" in our bank and I really do not have the time to make the signs, copy them, cut out mats, etc. and then distribute; but I can order new signs and send them to the branches out of town when someone goes that way.
Not to be taken as an endorsement for the company, I am sure there are others that do the same thing. You might check with Marketing to see who they use.
