Help me cremate my baby

The worst thing happened at 2:30 am. I woke up to see the dog had snuck out. I ended up finding him hit in the middle of the road down the street. Some poor excuse of a human hit and killed my dog and didn't even pull over to try to move him off the road. I'm not financially stable right now and I HAVE to cremate this dog. He was my best friend and I'm so devastated I can't say in words. If anybody can help or share this, if you can't, I'd appreciate it so much. Thank you, everyone.
