Got a call yesterday to do a one-time edging job, that will likely turn into a full-service maintenance contract. Went today to look at it. Here's what it is: Total of 880 linear feet of edging, of which about 120 feet is sidewalk where the grass is growing over the walk by about 3 inches. About 160 feet is blacktop driveway. The rest is reasonably well-edged brick walkways and beds. I know my hourly $$ requirements, but I'm befuddled by the overgrown sidewalk and the blacktop driveway. I'll be using a stick edger. Two-part question: Are there any tricks to minimizing the labor involved? and How much time do you think I'm looking at for the walk and driveway? A little help, huh?
