Help My parents get back to Colorado

Hello, My name is Joseph. I am the son of Mitch and Radna, who are my parents. My father recently had an accident a couple months ago. He slipped and ended up cutting his foot, which became infected. He went to the doctor and had it looked at, and the doctor advised him that it was gangrenous. Unfortunately the infection spread and he had to have his leg amputated. My father is no longer able to work, and my mother is retired also dealing with her own health issues. I am trying to raise enough money to have both of them move back to Colorado where they will be around family who can help them both with care.
