Audio DSP PCB Design Needed

I need a complete board designed around an audio-grade DSP that will sit at the heart of a home audio system. The board must include on-board equalizer control as its core feature and run from a stable AC-adapter input—no battery support required.

Here is what I expect:

• Schematic capture and component selection for the DSP, audio codecs, power-supply stage (AC-to-DC conversion and regulation), and all supporting passives
• A space-efficient, low-noise PCB layout ready for fabrication, delivered as Gerber, drill, and assembly drawings
• Firmware or register-map settings that enable the equalizer section, along with clear documentation on how to tweak bands and presets
• A complete, production-ready BOM with manufacturer part numbers and sourcing notes
• Basic bring-up and test plan so I can verify audio performance once the boards come back

Please base the design on readily available parts and keep all documentation clear enough for a contract manufacturer to follow without extra clarification. If you have previous work in audio-centric DSP boards, especially those optimized for home listening environments, that experience will be a plus.
