Analog Signal Processing PCB Design

I need a compact PCB developed for a one-off project that focuses purely on analog signal processing. The core task is to turn my hand-drawn schematic into a production-ready board, taking care of component selection, layout, and routing while keeping noise and crosstalk to a minimum.

Here’s what I will hand over:
• My rough schematic, functional block notes, and preferred connector footprints.
• Target board dimensions and basic mechanical constraints.

What I expect back:
• A cleaned-up, fully annotated schematic (Altium, KiCad, or Eagle—use whichever you are fastest with).
• Optimised PCB layout that respects analog best practices: short high-impedance traces, solid ground planes, and clearly separated power and signal paths.
• Complete BOM with manufacturer part numbers and availability checked.
• Gerber, drill, and pick-and-place files ready for fabrication.
• PDF plots and 3D model for a quick last review.

Once I verify your Gerbers match the design intent and the BOM parts are orderable, the job is done. If you have experience squeezing high-quality analog performance out of tight boards, I’d love to see your approach.
