I had the best luck with the following query:
Metacrawler query: Braille signs by mail
http://search1.metacrawler.com/crawler?general=Braille+signs+by
+mail&method=0®ion=0&rpp=20&timeout=15&hpe=10&format=1
Put that all on one line as the URL or location to open.
Or try:
Welcome!
http://www.signweb.com/signweb/welcome.html
If you don't have a web brower, here is a sample email addresses
for businesses I found by searching the Web:
