I think this maybe a newbie question but advice is always great. I have a new product I am currently in the process of developing. The product is an electronic product that in natures uses a lot of basic components found in cell phones and computers. My problem is putting everything together I don’t have a prototype yet, I really need to have the design refined before that can be accomplished. Right now I am looking at cost of production. My question is when thinking about components and a manufacture do I need to buy the components from suppliers, if I need say a plastic item made I need to have that made and once all sourced have all materials sent to my manufacture of choice? How do I get from idea to souring to manfacturing to market?
