Fundraiser for my step fathers funeral costs

As all of my friends and family know, my step father who has been the only father I've known has passed away on Monday. He was an amazing father, step father, and husband. He was exposed to agent orange in Vietnam and that's why he ended up with this rare blood cancer. And after 2 years of battling it, doing chemo treatments every week he just couldn't handle it anymore. We had to pull the plug Monday around 137 pm. A day I will never forget. Unfortunately myself nor my brothers have the money to pay for his cremation and expenses for the memorial. My mother already had to make funeral plans for my biological father when I was a baby so that's why I'm taking the reins on this. I would never want my mother to have to do this a second time. Our whole family greatly appreciates any help we can get.
