Hampton, VA new

the house is modular, built with 4 pre-built sections. basically, boxes connected together. it is 2 level and we want to open it up by removing (or shortening) a connecting wall that holds the "boxes" together. We have current floor plans and the vision for how it should look.
Need to get the structural, mechanical, electrical etc permits, so Im looking for a person to get this done. The house is in Hampton, VA.
