"There are specialty companies for this type of purpose, seriously."
I suppose there would have to be. I actually knew a lady whose job it was to clean up after dead bodies that had been left there for a couple of weeks --- generally shut-ins, but you'd be amazed at the mess a person makes dead on the couch for a weekend sitting in front of the TV (worked as a landlord --- guy was dead on Friday and sat there until Monday PM when people at his work started calling asking where he was.). UGGG.
I don't know how anybody could do that job.
