Hi Joe ; Welcome to Permies!
I do not know if grants are/were available, my gut feeling with the current administration is if their was grants … then that program has probably been cut.
Aging farmer's who have no one to take over after they are gone, might work out a deal. The problem is finding those farmers (notorious stay at home folks) then gaining their respect about yourself and your ideals/ motives.
I would say you need to be living in the area. Finding ways to meet these folks and getting to know them.
Volunteer to help your older neighbors . Make yourself known in the community as a friendly , polite hard worker. Talk to folks, slowly let it be known you want to learn about farming. Some old farmer down at the cafe will hear about it and let it be known he could maybe use some help... unpaid of
course... The food you get fed working on a farm is always plentiful and good.
Make yourself indispensable ... beware farmers daughters :) they will get you in
hot water really fast.
If you can do these things, then maybe you might be glad you did 10 years down the road.
