JR I have checked with about 15 pond owners in that area (surrounding 50 miles). All but two dug out their own pond (to have dirt for their house foundation). The remaining customers both had a "family" pond that had been around for as long as they could recall.
Sorry I have not had any luck, but I will keep trying for you. Like Greg said above maybe you can get a list of contractors in that area, and then require a list of customers from each contractor. Each pond should be built to the individual customer's needs, but there are some rules that must carry through on each project.
Hopefully I will find you something soon.
