My ballpark rule of thumb....a turn-key pond professionally built is "about $10K per acre of pond...maybe a bit less".
Of course there are lots and lots of variables.
5 acre pond $40K-$50K
10 acre pond $75K-$100K
so B.D. if you can get a 12-15 acre pond built professionally for the price you've been quoted that would be pretty awesome!
