Help Cover Rent for Injured Son's Recovery

My son was hit while crossing from Meijer to the mall on 7-20-24, by a car going over 45 mph. While he was very fortunate by not having any broken bones or internal injuries, his knee was really messed up and his arm. His injuries have made it so he is currently not able to return to work yet. He is mostly healed now but unfortunately that leg from the knee down is still not healed enough for him to even be up and moving more than an hour at a time. He really wants to get back to asap. I personally think it's going to be another few weeks as I am requesting an MRI on that leg because his foot swells up like a balloon when he tries to walk. I think if we can just get enough to cover his rent for two months I can cover his other bills and food. Anything you can help with is appreciated.
