This is NRidley's TrustRating, which is based on both the number of reviews NRidley has written, and how many other people have voted those reviews as "helpful." It's a way to quickly to determine the value of any single review or reviewer, because it's based on how helpful NRidley has been to the Kudzu community.
Signcraft designed a street sign for our department - it was two sided (different messages on each side). It was done well, finished very quickly, and was the best price I had found. I highly recommend them.
