Help to give dad the services he wanted

As you may know, my father passed away last night after his long 9 month fight from Covid. He’s always told all the family when he passed he wanted to be buried in a mausoleum, right beside his mother, my grandma. After speaking to the funeral home today it’s a lot pricier than we could’ve thought it would be. I want to do everything in my power possible to give him the services he wanted and deserves.
