What part of Alabama are you in? And what breed of horses are you familiar with?
Without having an idea of where you are, it is hard to help you with this.
Do you drive? Can you go off to shows with a string of horses? Are you responsible enough to sit with pets and horses?
What can you do? Do you know how to muck stalls, safely halter, understand that a trainer will want things done a certain way, and only a certain way? Do you mind getting dirty? Can you take tack apart to clean it and get it back correctly?
You can contact equine vets to see if they know someone that might need barn help? Can also check in Yellow Pages for barns too, and go see them.
Can see if there are any AL FB groups too.
Horses make me a better person.
