I have a client who would like to light a tree that is approx. 35ft high and 15ft wide at the base, what would you charge for this tree? If possible, how did you arrive at your number. I am new to this Holiday lighting and am trying to figure the best way to charge. We thought about renting the lights to our customers, but I see many people saying they charge a material cost, therefore the customer is purchasing the lights. Any advice would be helpful.
