You have an idea for a new product who do you go to to make this product reality and which type of manufacturing company would produce this product?

In many instances IP (intellectual property) is more valuable then who manufactures it. Protect yourself before going out and sourcing a manufacturer. There are 100's and usually 1000's of companies who will make it. The problem is getting out of it what it is worth. This is the key, not who will make it.
