Our Burro was "nameless" at the request of the former owner, so since I had a brochure printed about the year 1999 or so with a logo on it I decided to ask a local sign company to duplicate it. No problem, and they came up with colors that were pretty close. The vinyl product is quite easy to apply and appears quite durable.
The large and aggressive sign on some of the Burros did not appeal to me so they easily scaled it down to something I could live with. They now have this on their computer so it can be reordered and duplicated with a phone call.
Since a pair of them cost less than $30 I ordered a spare set for when I sand the thing down and
paint over the gelcoat.
Any decent sign company could do the same for you.
