Window sash (Ulster Park)

Over the next few months I will be replacing all the windows in my house. Most of them are replacement windows, and I will not save the frames. But I will have a quantify of single-glass sash, all divided light, mostly 6 panes each, 24-36 inches wide. In addition I will remove a couple of large units approx 4' x 6.5', essentially picture panes. Please let me know if you're interested, and how many you'd want of each size. This project will start around April 1 and run for a few weeks. One party has spoken for 5 or 6 sashes, but there will be about 50 of various sizes. the larger sash is about 4' x 6.5',; there will be 3 of these eventually. Others are from roughly 24 x 16 to 32 x 22; there will be at least 50 pieces of these smaller sash. All are 1-3/4" thick AFAICT.
