Support for daddy

My husband and I adopted a sibling group if three children. They are now aged 5,4 and 2. We also have two dogs that also mean the world to us and especially my husband.

He has been in intensive care for the last week after becoming very unwell and having seizures that left him in a coma. The future is very uncertain and he remains very poorly and fully sedated and ventilated. 
He had started his own company a few months ago and as this was taking time he didn't have a wage coming in. 
I'm trying to keep a routine for our children especially the eldest who has additional needs. Unfortunately family support is limited due to health difficulties. 
I'm raising money to fund perhaps an au pair that could help with the children having consistency for a short time following as suggestion by another adoptive parent. 
I'm also trying to ensure our dogs are looked after during this time. 

Any help or advice would be appreciated
