Whoever is doing the job, make SURE they bring you a copy of the insurance and bond to KEEP; not to just look at. I'd make sure you mention this BEFORE anyone agrees to come over. And when the DO come over, make sure you're they're there. I've heard stories where they say they'll come one day, and not show up, but come a day or 2 later when you aren't there and start the job. At that point, you could be at their mercy.
