I need to assemble a widget for an interactive piece of theater

Looking for a London-based hardware maker with experience in ESP32, LED control, haptics, and enclosure prototyping. Bonus if you’re into retro/interactive design. Goal is to prototype a handheld controller with crank, LED buttons, and sensors.
I have the project thought out in ChatGPT and most of the pieces sourced. Need someone with experience to assemble this and program it. Happy to go with another design if the GPT thing isn't up to your specs.
This is for a hybrid live/metaverse musical and the widget will control the audience's interaction with the piece.
We are a disability/accessibility forward production with funding.
If you want to be involved in the future of interactive theater and entertainment, please get in touch.
Happy to negotiate price.
Here's a list of components suggested by GPT (based on my needs):
1. Hardware Components
You'll need:
Microcontroller (e.g., Arduino, ESP32, Raspberry Pi Pico)
Haptic Feedback Motor (e.g., vibration motor or haptic actuator)
LEDs (RGB or standard)
Buttons (momentary push buttons)
Rotary Encoder / Crank Sensor (to detect movement of the crank)
Wireless Communication (Bluetooth, Wi-Fi, or RF module)
Power Supply (battery-powered or wired)
