So you have a design based around arduino connected to some parts on an adjacent perfboard or similar and now you would like to turn that into a custom PCB and make a dozen copies?
A lot of us can do that for you. You can see designs I have done at www.crossroadsfencing.com/BobuinoRev17
I can design the board so you can easily assemble it with thru hole components, or SMD if you have more soldering skill.
Bare boards are not expensive, and I can supply a PL for your to purchase.
Or I can build the boards for you.
