We have a modular sectional couch from pottery barn that was purchased 2 years ago. We are currently remodeling our house and the couch will not fit in its new room. The couch is in like new condition and we would like to avoid purchasing a new section. We are looking for someone to modify two of the pieces to move the arm from one section to another section (in the included picture, arm on the piece shown on the right needs to be moved to the right side of the section shown in the left of the picture). I believe the modification is relatively strait forward for a professional, but we have no idea where to start looking for help. Does anyone know who does this type of work?? Thank you in advance for the advice.
