Dads cremation costs and travel

My dad suddenly passed yesterday in a terrible multiple vehicle accident and passed on impact along with his semi truck catching fire . My mom was a stay at home mom with a few side jobs, he was the only source of income for them ... he will be cremated due to the severity of the accident . I live in Minnesota my mom is in Florida and the accident happened 2 and half hours south of Chicago .  Anything will help if anyone is able to .. I never thought I would have to make this or any of these arrangements anytime soon . 

I love you dad!
