I'm not a pro well man, just an old DIYer.
If it were me, I would just hand-drive or wash down a new shallow well point-and-pipe and hookup a new pump and pressure tank to it. It is highly likely that an old galvanized well pipe and more likely the old perforated well point are corroded up badly after sitting for that long anyway.
Check with your local Health Department for shallow well (25' or less from tip of point to pump) information and recommendations. You will need a permit from them for a well in any case.
When I have put down shallow wells down here just south of you, I always have used a 5' point and 3 five-foot 1.25" galvanized joints of pipe for the well, and add a check valve to maintain prime on the well side of the pump
I would go with a 3/4-hp pump (instead of a half-horse), which is what I did last time I put one down, so I could run two water hose sprinklers with good distance at once.
Good Luck!
Down here, a turn-key shallow well job by a plumber will run about $700. You can do it yourself for a little more than half of that.
