I charge a customer $45 to mow. edge, trim and blow his 1/3 acre lot...what would you charge as an annual contract to include shrub trimming(3-4 times a year), fertilization (4 times yearly), spread 5 yds of mulch in his beds, pick up leaves in the fall (minimal trees in his yard), aerate and seed annually? I priced it at about $2900 a year ( we mow about 9 months a year here/ 4 times a month)...that worked out to $240 a month....high. low, average? Any suggestions.....?
