Architectural drawings for shipping container home

I am a marketer who is working with a contracting firm to build shipping container homes, starting with 20 foot container homes. I need an architect who has worked on shipping container homes and who can work with us to build the interior and exterior design, and figure out the best layout. We want to create beautiful modern shipping container homes, that give people a great experience, but also have enough space for them to move around. It needs to include a kitchenette, bathroom, murphy bed and other amenities. We also ask that the person designing the plans be able to help price everything out so that we can give customers accurate quotes.
