I am bidding on a job to remove sod (2800 sq ft). After the sod is removed I have to level part of the ground, The yard has about a 5 degree slope with many humps. The customer wants 10 railroad ties cut to match an exsiting curve in the concrete (about 12 cuts to make the curve) After that weed barrier and Gravel (about 25 tons). What is a fair price? The materials and the equipment is about $1100.00. Is $1100.00x2 fair. Total Price of $3300.00??
