Design form shipping container conversions -- 2

I am looking for a design for a shipping container conversion that I intend to use commercially. Specifically, I want the design to include bathrooms and kitchen within a 40 ft container. I have specific requirements in mind for the design, and so I am looking for someone experienced in this type of project who can meet my specific needs. The end result should be a versatile shipping container conversion that is suitable for a commercial environment.
