Help raise for cremation & ceremony

Hi, my names Emma & I’m one of 8 out of my dads children. My dad was recently hospitalized the night before Thanksgiving due to covid-19, after two long weeks of him being in there he passed on December 8th. Everyday he kept saying he was feeling a little bit better so we all expected to see him come home. No one was prepared for this. Because this was so sudden & unexpected my mom currently cannot access his finances and won’t be able to for some time. Anything helps as we would like to lay my dad down how he wanted to.
