I'd try to help if I was there, painting walls never really bothered me to much, but the ceilings...now they are a different story so someone else would have to help out on them. Note I said try to help. I might be more of a hindrance than a help.
The primed wall looks pretty good, getting close to the finish in that area it seems.
Trying to help would likely be enough. It was nice to have the pro come and redo some of my cockups :D
