Hi there,
This is Bogdan from Romania.
I'm a mechanical engineer - specialized in the industrial robotic field, 3D designer and modeler (from time to time and some projects I could make the functional prototype too).
I'm doing product design, industrial design, reverse engineering, ideation, etc.
I have over 15 years experience working on various systems/devices across multiple industries, from concept to launch.
1 - in the first place i will need to know all the functions the device will have (what components, what for each port, etc, etc)
2 - the 3d model will be created and adjusted based on your drawings/sketches/requirements
3 - the output files will be ready for prototyping/manufacturing
4 - i strongly advice you to go for prototyping in the firs place, "play" a little with the prototype, see what would you like to change, adjust, modify - do this if necessary, and just after go for production
5 - i could help in many different other ways... (finding the best manufacturer through the portals where i'm registered, part of the patent application - prior art research, claims articulation, drawings, etc, prototyping in my own workshop, etc)
Regards
Bogdan
