The problem with a "hard price" is that any smart dozer guy will have to build risk into his cost. You never know what you are going to hit when you start a pond project. I think it's better to find someone who has a track record for doing good work and who you can trust. That way you pay for what you get and it's fair for everyone. A job can take 2 to 3 times longer than expected due to rain, hitting springs, big bolders, sand , etc. etc. etc.
Plan the project. Have test holes dug so you have a good idea what's in the ground and find a pond builder who can show you work he has done and talk, talk, talk to his other customers.
I was lucky to get a great guy here in New York and we were able to both envision what I wanted and I got exactly what I wanted. CLick my home page to see photos of my pond.
Good Luck!!!!
