Getting PCBs made?

Howdy!

Our property is fairly … complex. We’ve got five separate buildings, some with multiple sub-panels. In order to cover everything, I’ll need at least 10 IoTaWatt systems. That starts to get into volume discount territory with online PCB shops, and I’d like to explore that path. Has anyone done this? I’d love to get a bit of guidance on how to go about it, ideally with the components placed by the PCB shop so I don’t have to solder the surface mount stuff myself.

Would very much appreciate any guidance!!!
