Location is everything but I'd probably be in the high 30's to low 40k's, but that would also include subbing out the trenching and marking it up 30% if the customer didn't want to hire a excavation company. I always give the option of taking care of the digging themselves. Most take it when they find out how much they can save. I will also let them save more by getting their own lights. I will supply linear tube fixtures and a select few styles of outdoor lights. If they want something different, they have to get them with the understanding that I won't warranty them.
