I have not had the oppotunity to do much shrub trimming yet, just a couple real small jobs. Until now I have a residential customer that has an approximately 150 ft. row of shrubs he wants trimmed, they don't look like they've trimmed for well over a year. My question is should I charge more for the first trim since there so overgrown? How often should I trim them after I do it once. What would you suggest for pricing. Thanks for any help!
