Hi Mac, Welcome to PB!!! You will get good advice here by others. It just may be a bit slow because of the holidays, give it time.
There are many members that have a large pond like what you plan. You will want to hook up with some of them for advice, especially if they live in your area. They would have a better idea on what hoops you may have to jump thru. Like snrub mentioned, you may want to tread carefully until you get some advice thru members who have been there.
