USB Controller Setup for GameSir

Hi, I want to modify a wired game controller (GameSir Tegenaria Lite) by fitting a Raspberry Pi Pico and 2 gyro sensors inside it, based on this open source project with full instructions and wiring diagram:
https://github.com/steviegalluscio/alpakka-lite

I'd also like one extra thing included that is not in the official guide: 2 small touch patches on the top edge of the controller, as in this PHOTO:

Each patch is a small hole in the shell with a wire passed through and held under conductive tape, and the other end goes to a spare Pico pin. The wiring is the same as the touch point in the guide. I'll handle the firmware myself.

I already have the controller and will supply the Pico, the 2 gyro sensors and the conductive tape. Would you already have the small items, such as 100k resistors, thin stranded wire, an M3 screw, electrical tape, hot glue and solder, or should I bring those too?

Is this something you'd be able to take on, and what would it cost for labour?

Thanks,
