I would never do a wall fish for $13 as a contractor, as an employee, I don't know, if they are going to supply the van/gas/tools/liability if you fall through the ceiling, then maybe. I generally charge minimum $60, up to $100 depending on the situation.
Never argue with idiots, they'll drag you down to their level and beat you with experience
