RFL, here is another source for a company that does this kind of service. No machines available to buy. There is some small info on their process scattered around on their site....
service.. I just might have to give them a call sometime to see if they have done work in my area and check it out.
Interesting. It would be nice if they would show some of their equipment.

Well, I had a chance to call these guys today. They have a daily fee that they figure by, so it is a matter of how much they get done in a day. They average a 1/4 acre 1' deep per day. All in all, the estimate for your pond would be $27,700. I also have requested for some referals. If there is anybody near me, I will check it out.
