PCB Design

I would like you to design a motherboard PCB. About the board: This motherboard will use a Raspberry Pi 3 compute module to operate. This board will add the following: Display connectors, video circuitry, Sound, Input peripherals, USB ports, safe shut-down circuitry, emergency shut-down circuitry, charging circuitry, bluetooth, latency circuitry. I need the board to output high quality sound so I will need you to find a sound chip. I need it the board to be less than 8mm in depth and preferably as thin as possible. Concerns I have for this project: Connecting and using the Samsung display. Finding a good low profile sound chip. Guidelines: 2 Elco connectors will be used to hook up the Samsung display. A Micro SD card will be used to boot the system. A USB type-C port will be used for charging the batteries and have access to the storage as well as debugging. 2 slide potentiometers will be on the board. There will be one on the left side which will adjust the volume and another on the right side that will be reprogrammable to operations such as screen brightness, screen contrast, video scaling, color, and CPU clock rate. Screen brightness by default. Parts I found for this project: 2 of these slide potentiometers: [login to view URL] 2 of these speakers.
