I have a nice TB mare that is for lease and I am in Central Pa. Not too far from you. Here's the link to my post about her. Awesome TB Mare for Lease/Shareboard in Central PA
She's well started but I've only done lower level stuff with her, while she definitely has the ability to go much higher. I had her leased out to a girl that pretty much let her get away with everything and then the girl got frustrated with her. I was bringing her home to reschool her and then maybe try to re-lease her or breed her. If you're looking for a talented horse, that needs a bit of schooling/conditioning and is a very fun ride then let me know you can try her out since you're so close. She's located in Lancaster, Pa right now but she will be back in State College, PA by the end of this month.
