Guess what, my borehole has sunk today, the professional is asking for 1000usd to retrieve it. What else can I do we don't have water in the farm for us and the animals

Pay a truck to delivery water and have large tanks.

I paid about 4000 US dollars for a well back in 1980. Depending on the depth of the well, and more it can cost 1000's and 1000's of dollars for a well.

You pay the man for the well and get water. That is about all you can do.
