Electronic Engineering, PCB, and Prototyping

I have an idea for a product that I would like to create a prototype for. This product has advanced functionality and will require engineering to build. I have someone to do product designs and 3D renderings, but I need someone to work on the technical/engineering side of things. My goal is to eventually bring this project to market, so I need someone who can take the idea and bring it to market. If you can help with the engineering, please submit your proposals. I would like to do this for equity if you are interested. Note: I already have someone for the 3D design and product design. Skills required: - Electronic engineering - Electrical engineering - Mechanical engineering - Prototyping - Programming - PCB layout - Electrical circuit engineering Knowledge of nanotechnologies is a plus. Thank you
