Laying mom to rest

We all work but we all live pay check to pay check.  my mom was 50 and in ok health her death is completely unexpected. We are doing a basic cremation and then planning a memorial later on. We just need to get her body taken care of, so we can focus on saying bye to her soul. I hate to ask but we only have 6-10 days to come up with his money any donation is appreciated. A basic cremation starts at 700$ but that not including any hidden fees.
