Dad's Funeral Expenses

My dad's health has deteriorated alot in the past couple of months. He has been diagnosed with kidney failure and has been on dialysis for the past few weeks. At this time, he is unable to get dialysis due to his blood pressure being too low. At this point, they are discontinuing all treatments. He also suffers from liver failure, liver cancer, and heart failure. All his major organs are unable to be repaired. At this point in time, they are giving him about a week to live. Hospice is coming in to provide comfort care.  My father does not have life insurance and we need all the help we can get. His wish is to be cremated like my mother whom we just lost in October. This is so hard on our family and there is alot to take care of and no money to do it with. Please help with any donation you can no matter how big or small. It is going to be around $3,000.00 for everything.
