High end restaurateur seeking low end pricing.

I just looked at a job for a small electric sign at a bank. They don't want a permit, but want to know if I'd do it anyway.
The last "electrician" hired to install holiday light strands on about 8 trees for year-round use, pulled power from the site light posts.
He attached a wp box to the pole base and spliced SJTW extension cords inside it. Then he buried the cord a few inches in the ground to get to the trees. Up the trees with the extension cord to a 4-way "cube-tap" to pug in the light strands. At one point, the cord even goes under a concrete walkway.
All of this is in a nice suburban area with pedestrian traffic. (Of course no GFCIs)
Since the holiday lights have all burned out, they also want to know if I'd like to replace them.

No & no.
