I believe TV gets their windows, doors and garage doors from Ro-Mac. I once had a crack in one of my sliding glass doors and my handyman Tim Miller, got me just one side of a 6' glass slider from Ro-Mac for $153, which I thought was a good price. In fact, I think Ro-Mac has a window and door factory in Leesburg. I would call them Monday and just ask. Here's their website, they have locations on Rolling Acres Rd and in Leesburg.
