My photographer father is dying

Last sunday my world was shook to the core when my father sat down and told me he has stage 4 colon cancer. Hes at peace with it and that gives me some comfort bet we face large obstacles along the way.
My' father is uninsured and now uninsurable with his condition. I have never did a fundraiser so I dont really know how. I just know I want ro try my best to help him pay for Drs, meds, and maybe even leave a little something behind for his grandkids. Any ideas, thoughts, comments, or critiques would be appreiciated greatly. Thank you for your help!
