why don't the church or the other parishioners do a local fundraiser? it is not that much money and should be easy to raise.
best of luck
I don't know if the American Liver Foundation has funds available or not; they might be a place to begin though:

They also maintain a helpline: 1-800-465-4837
If they can't help directly, they might have some thoughts to share. And check back here too; others may stop by with thoughts and ideas. Thanks for caring, and good luck to your parishioner--
