Weed killer about $100.00.The lime depends on how acidic your soil is. I but pelletized lime which is more expensive per ton then regular lime. $10.00 a ton I think you are way off.I bought enough pasture mix seed to do 1-1/2 acres for $120.00. The fertilizer is another expence. I don't have the exact fiqures it was split up between 3 people but it is going to be more than you are thinking.
