Sorry to see this Amy, such a shame after such a long wait!
As Andy says, you could get the interior flocked pretty cheaply, and I dare say if you give them a ring and tell them the story, you might get yourself a great deal from them, as most of the cost in flocking is labour, so they might take pity and do a really knocked down rate for you.
Afraid I have to agree with the others with respect to selling it, I think you will really struggle. I would start off by ripping out the interior, strip it back and flock it. See Craigs car, it looks amazing. Then look to get some new seats etc. I have a pair of leather ones that need a retrim, but they could do you as a replacement for a while. Will look better than the interior I remember your car having. I also have a spare steering wheel that you could look to get retrimmed at some point. Open to offers on them, but would be collection only.
