I did graphic arts in High School and we had a lazer cutting machine that you'd load vector images into via ZIP drive. Would cut plastic stock up to 3/16" and with a very nice resolution and clean edges. Perhaps you could ask around some graphics shops, sign shops in particular, and get a product made. As far as metal ones are concerned I think most prototyping businesses or metal shops could get you done, but for more than is probably worth it. There's always acid etching, but I'm guessing you're looking for something more on the bold and clean side, huh?
