Navy veteran and recent amputee needs help.

My husband is a disabled veteran. He had his left leg amputated in January 2022. We have had to do some modifications to our home in general, and the VA has helped with a grant, but its not enough to make our bathroom accessible for him. We need approximately 4500-5000$ out of pocket to pay for what the grant doesnt cover. We are both on fixed incomes, so we have a budget that is not too flexible. Our families have helped, but we are still short. Any help would be greatly appreciated.
