Hello. I have a total of 3,500 sq. ft of sod that I need installed. I have removed about 2,500 sq. ft. of the old, dead sod and theres about 1,000 sq. ft. remaining of dead sod that needs to be removed. I purchased the new sod and the trimix and it will be delivered next week (I still have time to adjust the delivery schedule). Whats the cost to remove the remaining old sod, rototill the soil and install the new sod?
