If I were quoting the job I would bid $20.00 per 1000, a discount for the larger area. $50.00 for 2 soil test. Your total out of pocket should be $540.00 for seed, starter fert, if seed is obtained at $0.93 cents a pound, and the charge would be $1250.00. If you have a pull behind that would do a good job you may adjust the price if you feel you need too. Remember, your expense is around $8.40 per each 1000 sf, so don't under bid.
