My husband and I are antiques dealers and we go to a lot of estate sales. I recommend Lawrence Martin with Future's Past estate sales and appraisal services. He is an accredited member of the Dallas chapter of the International Society of Appraisers. He can do a formal written appraisal and conduct an estate sale. I'm sure he could make arrangements to have the items moved to another location if needed. His website is http://futurespast.com/.
