This is noonmurl's TrustRating, which is based on both the number of reviews noonmurl 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 noonmurl has been to the Kudzu community.
Even though the service was good, the price they charge is not. Very over priced. They should tell you up front how much they are going to charge you. They wait until after they do the job to get your money.
