I'm very transparent about my prices, mainly because i know my competition have thier friends get me to do bids so they know how much I charge. hiding anything just costs me time in the long run. I charge $25 per 100 light strand to install, takedown,and store the first year on the first 2000-5000 lights. beyond that you start to look at volume pricing, probably down to $18 per strand when you get above 10,000 lights or so or 100 starnds. timewise mini-lights can kill you. I recently did a job with 16,000 mini-lights, all on shrubs/ground and some in trees with poles, and it took 2 guys a day and a half to do the mini's. I charged 18 dollars a strand for new and 15 for existing lights. that worked out to around 2800 bucks for 2 guys for 1 and a half days, but it will take them probably 3/4 day to takedown. so 36 man hours for 2800 bucks is good money, but once you figure in the cost of cords, timers, and lights, maybe just 65 per hour or so. If you use high dollar 6-12 bucks per 100 light sets, you really need to be at 25 per strand and up. on rehangs I sometimes go to 12.50 per strand and sometimes have lower cost part-timers go ahead of the roof guys and mini-light the place. they will use thier car and can come and go. The roof guys for some reason prefer not to do mini-lights. whatever works.
