Advice on contractor woes

[Erin Margaret]

Hello there BP land! I am in the final home stretch of an intense 1857 historic rehab. We have been going since may and are down to just refinishing the floors and a few final touches. I hired a guy who came with decent references to refinish the floors over a month ago. He said the whole building would take 2 weeks. He has sanded one room and half of another and hasn't shown up since. I am not nearly as intimidating as I need to be so I had my father and my contractor both call him he has promised to show many days and is never there. I've had to push back the photographer twice now and I'm afraid getting deeper in to winter it is going to get harder to sell. Any advice on what I should do about this guy? Everyone else is booked out at least a month. Should I just rent a sander and see if I can do it my self? Sounds dangerous
