PCB Design for a music controller

I need a PCB designed for a Teensy 4.1 controller that integrates multiple functions.

I am building a controller to expand the functionalities of a musical device.

My expander expands with
- more memory with search, sort & memory switch
- LED strip, LED matrix display & DMX for visual features
- Controlling via RGB LED buttons, mouse wheel, QUERTY keyboard
- RGB LED buttons & TFT displays for 10 channels
- A master controller touch TFT

Essential components to include:
- 1 x Teensy 4.1
- 1 x IN OUT MIDI Control (with or without module)
- 10 x 2 MicroSD Memory switchboard
- 11 x TFT SPI Displays (1 with touch)
- 24 x Carbon grid touch SK6805 LED Buttons
- 4 x USB (with CH334 USB2.0 HUB module)
- 1 x DMX
- 1 x Bluetooth
- 1 x onboard Mouse Functionality (rotary encoder)
- 1 x onboard IR sensor
- 1 x adressable RGB LED strip
- 1 x Music LED controller
It also includes
- MOSFET switches,
- I2C IO expanders &
- TXB0108 shifters

Ideal skills and experience:
- Proficiency in PCB design software
- Experience with Teensy 4.1 microcontrollers
- Knowledge in audio and MIDI electronics
- Familiarity with integrating multiple protocols (USB, MIDI, DMX, Bluetooth) (with pre fabricated modules)
- Ability to create compact, functional layouts
- Knowledge in correct power handling & PCB lane design to meet correct power needs & interference avoidance
- Knowledge in stable memory handling
- Knowledge of carbon grid layer design for LED silicone touch buttons

Looking for a professional who can ensure all components work seamlessly together.

The solution is devided into
- 1 main controller PCB
- 2 x 10 channel button & LED PCBs
- 1 MicroSD memory PCB

I haven been posting this project to find the right candidate & price for this project.

I have a 170 pages Word document describing the whole solution, which can be handed out when a LOI / NDA document has been signed.
