For me, the cost qouted was around 15,000/acre. However the guy told me I had two acres, and I really had a tad over 1. That means the cost would have been 30,000/acre. Be careful of how they figure it and what you get in return. I ended up doing it myself, glad I did but a lot of work. Other variables that affected the quoted cost were: Renovating a pond, which always costs more -- depth quoted was only 8' -- all muck/dirt had to be hauled away.
