I Need Construction Work Done

Building a Recording Studio inside of a 1000 sq ft. already functional warehouse loft space. (Loft portion has been removed. The purpose is to create a soundproofing situation with walls that can be disassembled as this will be a flex studio space. Control Room, Vocal Room and Acoustic Room are the primary focus of this space. There will need to be a stage for the floor of half the facility (this as well to be movable). The ceiling height is 12ft. The building is concrete ceiling and floor.
