Hi there Anthony. If you can't get anyone to go with you to, you can go without a guide. Caving isn't nearly as deadly as some try to make you believe, and Pine Hill is an easy cave to navigate. If you equip yourselves properly, take it slow, and pay attention, there's no reason that you can't have a nice trip without a guide. I can send you a map of Pine Hill cave if you wish. If you have any specific questions about the cave or what you may need, fire away.
I thought of a nearby Ohio cave that you may be able to visit. It is called Frost Cave in Pike County. It's very short, but it has a nice entrance and is as good a beginners cave as you will find in Ohio. It's on YMCA property I think, and access should be easy to obtain. I'll look into that some more for you.
