How to manufacture a computer keyboard.

Hello All,

I have a computer keyboard design in which to companies in Spain has shown an interest at selling it so I am seriously considering manufacturing it.

Could anyone give an overview on how to find a manufacturer, costs, licenses, advertising, distribution,....?

I am sorry I am asking too much but I really don't have any idea about how to do business. I have plenty of ideas but no know-how to develop them.

Thanks. Eduardo.
