Usually funding on kickstarter is achieved when the person has lined up all the avenues for maufacturing their product ahead of time. Unfortunately almost every time that someone doesnt do this, the backers never see what they paid for. You do have to have some knowledge of basic manufacturing practices. Is your product injection molded? machined? Are there electronics? Do you have software that needs coding? Then you start building prototypes. Once you have a production ready prototype then you will start sourcing companies that can accomplish each task. Perhaps at the end of it a fulfillment company that will package and ship your product. For alot of people that means them in their garage taping boxes and driving them to the post office.
