Visit my grandpa in the hospital

My grand father has been diagnosed with an aggressive form of brain cancer. I live in Cleveland OH, and he is in Phoenix AZ. I don't have the money to afford a ticket to fly out and see him and can't afford to not be paid for a week. It's selfish of me, but I need to see him. 

He is a smart cracking jokester who is still smiling and having a good time despite his very serious condition. He's also one of the most generous people I've ever known and the thought of not being able to see him when he is i  ths condition is killing me. I've exhausted all other means, and have resorted to asking random strangers for help.
