Help for my Fathers Recovery

While taking his evening walk on January 4, 2017; my Dad was viciously mauled by three pitbulls.
The damage to his face and arms is very extensive. The doctors were able to reconstruct his face mostly. The bites to his right arm were bad, but the damage to his left arm is heavy and he may lose the use of it altogether. After raising 5 kids, they are now in their 50s and raising my 2 nephews. All the weight is on my mother to support the family, as my dad is unable to work. Please help as much if you can.
