Do you deliver your wood or have people pick it up? If you deliver throw a measured cord in your delivery truck and mark how high it comes up on the sides with spray paint. I sell 60-70 cords a year, never stack and have never had a single complaint doing this.
If you think this could work for you, just move your wood pile to a place that gets full sun and wind exposure to ensure proper drying. My piles are usually about 18' wide, 8' high, and up to 100' long on a good year. And from my experience, piles that run north/south dry better than ones that run east/west.
