I have to agree John. Around here it's about 15,000 per acre. But it could cost a little more for a smaller pond. After all it has to be worth his while to move equipment and time. If one can not make any money at pond building them I would stay at the house. $5,500 is not that much money these days when you consider moving in and out cost along with only a couple of days work. And since it is in Ohio, maybe things just cost more there.
