ok i never messed with landscape lighting. Im looking to expand into this field. I went on an estimate early today for a landscape design job. The job is small. The client wants me to upgrade her existing lighting system. The system works and all the lights, wires and etc. are installed. The client wants me to remove the 20 existing walkway lights and install a new set. Since everything is fully functional, i want to remove the existing lights and install 20 1 tier malibu walkway lights. The new lights i found for $75.00 and im figuring this should take me no longer than 3 hrs to do. My guess based on time, material and it is "extra" work i should charge her $300.00. Does that sound right???
