Prototype PCB run ~$300 for 1 or two PCBs to about ~$500 for about 25 to 50
boards where the lower numbers would be for a physically larger board. This
includes about $200+ for the artwork.
I use him all the time and have never been let down.

If you are paying $2K, you need to contact Don Skowronski
<dski@nutronicspcb.com> for a quote.
