>When you ask a large PCB fab for anything that isn't 1.6mm thick FR4 white-on-green and standard stackup
actually most of the china fabs (PCBWAY, JLC, elecrow, allpcb etc) include most of these options in their "prototyping" offers now.
some even have MATTE BLACK and controlled impedance at no extra cost. competition is fierce right now so it always pays to shop around (and not just using PCB shopper)
