If you actually want to make money on it you better just patent it, very lengthy, expensive, and time consuming considering you will need a good prototype "depending on what you patenting" There is soo many "ideas and theorys" patented with business's and their intellectual property its hard to find to come up with something that isnt already taken or in the works. It can literally take years and you can end up with nothing in the end. With my experiences of trying of patent things I just gave up on it because of these reasons and like you said it seems everyone is trying to scam you. Sooo with that said I hope you have alot of time to mess with it and good luck.
