This area is really tricky.
Not wanting to dispirit you or anything, but there is a saying that "ideas are free", and putting this another way round, ideas themselves don't have a monetary value.
In practical terms, an invention does not begin to have value until there is a working, demonstrable prototype with full design and construction details available. (This is the point where you would have enough information to hand to make a reasonable patent application.)
It is highly unusual to have an original idea in a mature industry. Useful ideas come out of needing to solve a particular problem, and are you the first one to need to solve this problem? If you are the first or only one facing this problem, where is your potential market? Now suppose instead that many people face this problem every day, then surely many others will have thought of your solution before you? In which case you have to ask yourself, why has nobody acted on it yet?
Are there some technical barriers to implementing this idea that make it impractical? Is it going to be so expensive to build that it doesn't save any money? These are all questions to ask yourself.
Now it could be that you have thought of a truly novel and unique solution to a problem that nobody really has come up with before, in which case you could succeed. In that case, you are the one with the motivation to see it through. Anyone you consult with will be commercially motivated and will want paying for their work. That's probably not a good place to begin. You can easily end up pouring lots of money down the drain if nothing comes of it.
I think you have two choices. Either find a potential partner in the same industry with the vision to understand the utility of your idea and also with the technical skills to help prototype it. But then what will you bring to the party? Or, you need to learn the required technical skills yourself so that you can prototype it and make it work. This will be a long and painful process, but you will be the better for it.
Needless to say, I think learning how to do this yourself is the best option. Only by learning the technical skills required will you truly understand whether your idea is really practical and also keep control and ownership of the idea.
