What part of PA are you in? There is a rescue near here (
Metropolitan Guinea Pig Rescue) Metropolitan Guinea Pig Rescue. I'm sure you would want to meet the piggy first, but maybe people in the area could do some type of "railroad" (transport chain, one person picks up piggy drives so far, the next person takes over, and so on until it gets to the new adopter). I live in the Baltimore County area (East side) of Maryland and wouldn't mind participating in something like this to help out.
But again, you would probably want to meet the piggies first, and that would require coming to at least the MD area (not sure where they have thier meets, as they are foster based). So, not sure. But again, I would be willing to help out if there are others that could do so as well.
