Help for Mom after dad died

On  January 24th our dad unexpectedly died he leaves behind my mom who was with him for 40 years and is now completely lost without him. We would really appreciate any help towards his cremation and service. Because it was so unexpected we don't have the money to give this amazing man who would help anyone no matter what and took great care of his family the goodbye he really deserves.  Dad went in for knee replacement surgery on January 22nd and did great everything went great. On Tuesday he got to go home we got him in bed and short time later he was sleeping.  My mom woke him up to eat but he wasn't hungry and went back to sleep my mom had a feeling a short time later that something was wrong and touched his arm and he was cold she called 911 they tried very hard to get him back but unfortunately they couldn't.  what I thought was a blood clot turned out to be an enlarged heart and his heart just stopped.  We have some peace knowing he went peacefully in his sleep. Dad was a Marine and received 5 awards while serving. He was very proud of being a marine. He was medically discharged due to hurting his knee the same knee he had surgery on 2 days before he died.
