Hello there! Now that I have a better understanding of the project's complexity, I'm wondering where I can find the right assistance to build something like this. While I am aware that there are companies offering such services, I am particularly interested in collaborating with someone who possesses in-depth knowledge of electronics and related subjects. I'm curious about how difficult it might be to find a "private" individual with the expertise required for this endeavor. Thank you for your help.

I think creating a device like the Sony HVR-MRC1 Memory Recorder involves combining hardware and software components. I am about a Firewire or Thunderbolt 3 port, a small screen, buttons, and an SD card slot. You also need to develop drivers, a user interface, and data recording capabilities. The complexity and cost depend on the design and quantity. And just consider legal aspects if using patented technology.
