Created a guide about six months ago on this exact subject (search for manufacturing on HN people have posted the link dozens of times). Still get asked questions a few times a months on here and via email on the subject. So there is definitely interest.

Other than myself I haven't met anyone that can take a product from concept through production so you are going to need a huge contributor pool. Also it's not having the information but understanding the process and cultures your dealing with. As an example a couple months ago someone on here contacted me for an idea: the main components were an LCD and the processor. So I told him to find a manufacturer already using those parts and then design his product using their base system. That way he could get scale pricing without having to purchase huge quantities. With my experience I knew what the key components were for his concept, where to look, and who to call. I don't think you can replicate that information in a guide.

Sadly right now I'm too busy to help much. But if you hit a hurdle on a subject feel free to email me with the question.

EDITED: Added stuff
