does anyone know of professional pond contractor with experience in putting in pond liners.i want to build 1-2 acre ond in very sandy soil. would like to find pond builder who has experience in dealing with such construction

One option is to contact a couple of large pond liner companies. They should know of common users/conractors in your region.

Option 2: contact Pond Boss co-owner Mike Otto's office. He will likely know of contractors who have worked with liners in So. Central US. 800-882-3478 or mikeotto@ottosdirtservisce.com

thanks much for your suggestion. i will try it.
