I was referred to Plumb Works by a friend. The plumber came out and wanted to charge me $750 to connect my newly installed sink and faucet. The sink was already installed, the water lines and drain were already present in the wall. All I needed was the faucet assembled and the faucet and drain connected. The estimate was completely out of line, considering I bought a kit for $40, read the directions, and did it myself in about an hour.
