I don't do much trimming so forgive me... A customer wants me to trim a row of Forsythia (sp?). It's 90' long by 8-9' high by about 7-8' wide. I know this is not the right time to trim and blossoms will be reduced in the Spring but they want it done. How long should this take to do? I will be solo, using 40" hedge-trimmer and an attachment trimmer (the pivoting one for line-trimmers). I will be taking off approximately 20-25% from sides and top, rounding it. The clippings will be carted to the woods in thier backyard. I'm figuring 4-5 hours. Should it take less. I don't want to overcharge... $200-$250 Any help would be greatly appreciated.
