interior stuff, leave it or DIY?

A really good local upholstery shop can take a few months to get this done, and I could have the car in their shop for 3 months or so. I was thinking of just taking everything out, and dropping off parts to be recovered there instead, and then reinstalling myself, down to the carpets.

I know FBB took just about everything off his car, lol. Can anyone tell me how difficult this would be? Got the gauges and door panels off already for other work, and just thought maybe doing the rest would be the better way to go. I'm thinking maybe slightly better pricing and less worry if I do it myself, but more hassle obviously, plus current garage space issues until end of the year, though could be worked around.

 

So that's one for DIY, of course from pap, lol.

Anyone do this, and wouldn't do it again, or offer advise on how difficult.
