Anyone know where I can get a job working for my lessons in Harrisburg/Hershey/Grantville/… PA?

I am fifteen years old and have been around horses all of my life. I had a job working for my lessons at a local farm from age 11-14. I have experience mucking, turning horses out, helping tack up horses for lessons, grooming, and feeding. My trainer recently moved away and I am now looking for another barn to ride at. I am a hard worker and am willing to do just about ANYTHING. Any help?
