Help my son fix his car

I am setting this up for my son who was driving back from Montana and his engine blew in the middle of nowhere by Hot Springs Montana. Josh travels to Montana every year to help his friend as a cook for an equestrian event that happens every July. On his way back from the event he was on the highway with no cell service and his car broke down. Thankfully he was able to coast to a house and the owner of the house was gracious enough to drive him 30 minutes into town where there was cell service to call his friend and stay the night. Josh was able to get his car into a shop in Hot Springs Montana where the car is sitting at this point waiting to get worked on. The engine is completely shot and needs a lot of work done to get fixed. Not only that but with everything going on with COVID Josh got a letter in the mail while he was in Montana that he got terminated from his job with Nike. So now he doesn’t have a car or a job which is why we are asking for any kind of help at all in a time where a lot of people are in need. It would be so much appreciated if anyone could help with anything.
