I need to give a price to somebody for re-doing the lawn. I know what most of my costs are and just need help with figuring it out. The area to be worked is about 15,000 sq feet which is HEAVILY compacted and packed full of small rocks. I will have access to the owner's new 20,000 lb excavator and 6x6 offroad vehicle which has a dump box on the back. My costs will be the glyphosate which is either $12.50 per 5 gal mix pouch or $67 for 83 gal mix pouch Hauling in some organic matter from other job sites which will be about $400 or so. 9,000 lbs of this soil conditioner stuff which will cost $1,500.00 plus tax Salt hay at $12.50 per bale Endophyte enhanced perennial ryegrass at $110.00 per 50 lb bag 450 lbs of elemental sulfur for $135.00 Labor which costs $100 per guy per day. 500 lbs of Roots at about $15 per 50 lb bag Any other numbers you need just let me know. The guy wants the job done right and doesn't really care what it costs so long as I am not ripping him off. If I do the job right... it is worth its weight in gold.
