I used to do Christmas light installations until I started getting crazy on my own house every year. There was usually 2 types of people that would inquire; 1.) Little old lady whos husband was unable to get on a ladder or had recently passed away or 2.) Filthy rich with to big of a house to want to attempt hanging their own lights. For customer number one I would hang the lights and in return be paid with some sort of home baked treat that was made from scratch and worth more than a check. Customer number two would be charged normal business rates.
