Thanks for your help anyways.
funny as it sounds the manufacturing I have all figured out (or so I think) I have a list of the parts that I need to find factories that do those stuff after finding them all I am left with is someone for the assembling.
But creating a prototype I am just not getting it, how can I make just one or two pieces while keeping the costs down, no one is going to make me molds just for 2 Pcs. 3D Printing is also not an option as I need some real large parts.
