If the house suddenly has no water, check the breaker and the pressure-tank switch before you assume the well is dry. A pump that hums and dies is often electrical or a failed pump, not an empty aquifer.
Call a company on this list and say you have no water. Ask if they service residential well pumps at your land. If the well has been weakening for years, also ask whether a driller should look at it.
Do not drop tools down the well. Do not run a dry pump on purpose. This directory does not dispatch anyone and does not invent a diagnosis.
After the visit, ask what they saw: pump, pressure tank, or the well itself. Keep the notes with the house. A mailing city still is not a coverage promise.
