Hi, I am planning to renovate a lawn. It is approximately 4000 square feet. I am not sure what type of grass is growing in there now, but it is a sort of deep green, thick bladed, thin spread grass which has taken over the lawn. I plan on spraying the entire lawn with glyphosate renting a toro dingo with the box rake attachment and tearing up the lawn. I intend to get a soil test, put down corrective lime as well as a starter fertilizer. I plan to put down a bluegrass/fescue mix and setting it in with a roller and covering it with peat moss. If the soil test shows it would benefit from mixing in compost, sand, or the like, I will do this at an additional charge. Right now I have down $800, but I have not sent it to the customer yet. I got this number from the following (at $60/hr charge rate) Materials: rental- dingo: $200 rental- roller: $20 glphy: $30 Peat moss: $50 (5 bags) Seed/fert: ~$100 Labor: pick up/drop off dingo: 1 hr Spray: 2 hrs labor for dingo: 1 hr roll: 1/2 hr fert/seed: 1 hr Keep in mind that I have never used this cultivator before, i am basing the time estimate off videos i saw online. I have also never sprayed such a large area but I don't imagine it would take that long (I included driving time in the estimate) I would appreciate any feedback on both my approach to this renovation as well as to the pricing. I read that you should til in 4" of compost- this seems expensive. for 4000ft2 that would be about 50 yards at $60/yard before delivery and labor.. I don't think this would be worth it?
