You need to ask the customer what he really wants. There are punchdown patch panels that are usually rackmount - read pricey. I have seen surface mount plastic blocks that will hold 4 jacks. In my house, I just put a couple of 2x4 boxes on a backing board and used faceplates with 4 jacks each. For the phone side, I used a "66" block and punched down all 4 pairs of each cat5. That allows up to 4 idependant phone lines. If you keep it simple, you can find all the parts you need at the local Big Orange Box. If it gets complicated, Graybar handles a lot of networking hardware.
