Due to the inherent problems of printing this size, and I was pretty sure that this would be a tall order, the customer now wants something completely different. Of course this is the way customers are. Sorry I couldn't spread the love around. Now I'm shooting seventy prints and framing them individually of the same subject so at least I've still got the job and will make about the same as I would have charged to facilitate the large print. Thanks to everyone for the insight and sorry it didn't work out for Elevator.
