I spoke with Matt today from Door Restore. Although I sell new doors to customers, sometimes it only makes good sense for a homeowner to refinish their existing door. 

I figured he was done finishing doors for the season, but Matt explained that he can still finish single entry doors all winter long. He comes out to your home and puts a temporary door in place of yours. He takes your door back to the shop and returns with the finished product. He is currently booking April appointments for double doors and doors with sidelites. 
Here is my favorite Before & After from their website.
