Coffee machine electronics+mechanical+design

As the client, I am looking for a mechincal and electronical coffee designer that is both aesthetically pleasing and functionally sound. The main material to be used should be metal and high-tech features should be incorporated within the electronics and components. My goal is for the design to have a modern appeal with electricity efficiency in mind. The materials used should also account for any wear and tear that may occur over time to ensure a long lasting design.
