If you don't have problems with funding, find a consultant to discuss and implement it. Reducing your idea to practice considering price targets, buildability, reliabilty, standards requirements might not look exactly like you imagine when it only had to exist in your head.

If you want to build hardware, start building hardware.

I mean literally.

Which means your initial ambitions can't exceed your plausible abilities and your roadmap: learn by doing.

Good luck.
