Old shallow well on raw lot - what should I know before choosing a pump?

I have an old shallow well on a raw half-acre in northwest Missouri. It has a wooden cover right now, no power on the property yet, and the old pump setup is rusted out and unusable. The pump that was there was marked for a 0-25 ft shallow well.

Visually, I think water may be around 20 ft down, but I do not have real measurements yet. A certified well guy is supposed to look at it soon.

My first use would be plant watering and land work, not drinking water. Long term, if the well is usable, I’d like a simple setup: maybe a small submersible pump, maybe solar-direct to a tank, maybe portable power first. I don’t want to buy a pump or tank before I know what the well can actually do.

What information should I make sure I get from the well guy?

I’m thinking depth, static water level, recovery rate, lining/wall condition, whether it is seasonal or drought-sensitive, and whether it needs cleaning or a better cap.

Anything else?

I’m mostly trying to learn the right order of operations. If this well can keep plants alive while the land gets developed, that changes a lot. If it cannot, I need to know that before I build a plan around it.

Wow, all that brickwork is pretty cool. Old mortar in the well casing bricks makes me nervous though -- a possible leaky sieve.

I would ask the typical depth of good wells in the area.

Based on the lay of the land, am I collecting good groundwater or runoff water?

Can a casing / sand point be put down to exclude runoff water?

And if there is a very shallow groundwater or runoff water, I would carefully consider where that might be coming from in the mile surrounding it.
