What other ways can I get big money for my idea besides patenting?

I have an idea for Ford Motor Company. I'm only fifteen and don't know a lot about the business world. As I have learned, the process of patents is an extremely complex thing. Even Adult business professionals find it stressful. If there's an affordable and simpler way to patent my Idea please tell me.

There's no easy way to get a patent - it takes a lot of research just to see if the product you want to patent is not already on the market

File a provisional ($65) and use the grace period (up to a year) to shop around your business plans to potential investors who may be happy to give you the money in exchange for a percentage of the up-side potential.
