I have a really good Invention idea to improve a current product on the market. Im not going to specify what it is, but does anyone know the steps to marketing my product? Should I go to a local patent lawyer and start there? Im in the process of drawing up and specifying all the details of my idea, material, sizes, colors, etc.

There is a company I heard was good named Davison that helps people step by step with their Invention ideas, anyone know.
