I have a customer that has 125 linear feet of hedges that are about 6 feet tall and another 214 linear feet of hedges that are about 4 feet tall. These hedges are about 12 inches thick and run around the entire property, from the front driveway, across the front by the sidewalk, turn a 90 degree corner and go all the way around to the back of the house and turn another 90 degree corner to run across the back of the property. As I said, they are about 12 inches thick, they use them for privacy as they are located on a busy street. All that would be involved would be trimming them horizontally to maintain their overall height as well as sheering vertically on the sides so that they don't get any wider. I have access to both sides of the shrubs as I'm either on their property or on the sidewalk property, and can walk all around the entire "hedge wall". It's kind of like trimming a total of 340 linear feet of the great wall of china. <G> I could put down a tarp on the side that I'll be doing most of the trimming from, but even using a 20 foot tarp would require moving it about 17 times.. (and when full, taking to truck, dumping contents and re-setting). So for these kind of hedges any kind of estimate on how long or how many "linear feet" this kind of job takes per minute or hour with 1 man, solo? I can reach the top of the 6 foot hedges as I'm 6'2 and I have an gas extension trimmer so I guess I can walk along and hold the trimmer up high (or use a short step-stool) and trim to make a nice flat-top. They are already trimmed and in decent shape, but the customer wants to get a price now as he knows they will need trimming by mid-June and again in late September. And I know he'll be getting other bids. I currently cut his grass as a regular customer.. Thanks guys!
