A customer wants me to dethatch, aerate, reseed, and put down gypsum. I was going to first dethatch clean up debris, aerate, then put down seed and gypsum. I have to aerate in order for the gypsum to get into the ground. THe lawn is 12,000 s.f. and the customer is supplying seed and gypsum. I am charging 250 for the dethatch, 85 for the aeration, 25 to put down seed, and 25 to put down the gypsum, for a total of 385. What would you charge for this, have you ever done something like this?
