If you have the equipment, turn it over after 2-3 months and after 2-3 more turn it and add organic matter such as saw dust or small wood chips....maybe spray it with Round-Up a few times during cure. After a year total, you should have good topsoil? ~$300/load here...$100 more if you sift it....cousin just cleaned out an old 1.1 acre pond and has probably 200+ loads.
