I’m getting ready to spin up a prototype and need an experienced PCB designer to turn my schematic into a clean, single-layer board that will end up larger than 10 cm × 10 cm. I’ll provide the circuit diagram along with a few placement preferences; from there you’ll handle footprint selection, component placement, manual or auto-routing (whichever gives the most reliable results on a single copper layer), and all the usual design-rule checks. Because this is strictly for prototyping, I’m less worried about space savings and more concerned with trace clarity, manufacturability, and easy debugging. Standard through-hole parts dominate the BOM, but a couple of SMD footprints may appear—nothing exotic. If you normally work in KiCad, Altium Des...
