I don't know enough about ground water ponds or your location to give you any advice, but will tell you the way I would approach it.
I would approach something I am unfamiliar with but seems like a good idea with the following questions.
1. has anything similar been done in the area and was it successful? (I assume it has since you mentioned other ponds in the area).
2. What could go wrong? In other words if it does not work out as envisioned, what could be possible negative consequences from the resulting hole in the ground.
3. I would want some assurances that the contractor would perform as promised. Is he reputable? Is he going to get what sand he needs with the hole in disarray and then never show up to finish it? Assuming he is a reputable person, I would want some written guidelines as to what the size, shape and surrounding condition of the hole he leaves. In other words if after half way digging the pond he has enough sand to fill his needs, he needs to finish the pond and stockpile his sand somewhere else anyway. You do not want him getting the sand he needs then leaving a half finished pond with huge ruts leading to it. He needs to finish up to your specs.
That is the way I would approach something I know little about.
