Prototype building

Hello everyone,
I discovered the VHS today during the culture crawl and it was a great surprise for me.
I will become a member soon.
I am preparing for building a prototype for an invention (just applied for a provisional patent) related to converting internal combustion engine into zero-emissions one by changing some parts of the engine and introducing some electromagnetic devices.
I need some help to manufacture these devices (turning machines and wiring solenoids) and some electronic circuit to control the engine.
I am thinking of building a first prototype on a lawn mower before moving to a car.
We can create a project team to work on this together.
If you are interested, please advise.
Thank you
