My dads old house was caked in Black mold in the basement. He brought out the old sand blaster and got to work lol. He completely removed all drywall, sandblasted the block down to basically bareness and started with all new shit. Only took him like 3 days to get it all done. If I had a scanner I would post pics. The columbus fire dept was called because they thought the house was on fire due to the sandblasting dust lol. If your wanting/needing someone to do it, shoot me a pm and i'll get your contact info and have him come look at it and give you a price.
