Big Bertha Needs Help

Hello, my name is Leslie. I’m the grandparent to all these children. I’m asking for help on behalf of my son, Eric and daughter in law, Melissa. They were having to use two vehicles to transport all seven kids. They had received a 1999, GMC Savanna to help transport all the kids. Unfortunately, Big Bertha has blown a head gasket. It will be an expensive repair and could use monetary help. Thank you
