I'm looking for a PCB manufacturing service that can do large 2 and 4 layer boards. Only need power planes, no signal layers on the 4 layer boards. And by large I mean up to A3 in size. Mainly for prototyping/personal projects. Delivery time isn't all that important, as in anything under 2 months is acceptable. My main concern is pricing. Silkscreen would be nice but isn't necessary.
