I hope I do not come across as too harsh.
I have recently been involved in some unfortunate issues involving both sides of estimating pond construction cost.
Each job is very different. Risks, travel time, heavy equipment site accessibility, permits, goals, soils, terrain ... they are all part of the equation. For example, it costs far more to move a hundred yards of dirt a half mile with a track loader when compared to a track hoe and dump truck.
Attitude of the landowner is also a major consideration. No one wants to be micro managed in their area of experrtise by someone who does not understand, and who is ever threatening with various forms of retaliatuin.
Get Extension Serrvice and NRCS recommendations. Get at least three estimates.
