Try:
Cyclepath 1212 South El Camino Real San Mateo, CA 650-341-0922
Although I've never shipped a bike through them, they otherwise seem reliable. They're a mostly high end road bike shop which coincidently has a very nice collection of restored NR/SR era bikes hanging on the walls (my main interest there).
