Quadrapelegic father in need

My father who was hit by an SUV  February 8th is in need of help. James Yearsley who is currently in the hospital was declared a quadriplegic, paralyzed from the chest down.  He is awaiting insurance through social security disability, which takes months.  We are trying to raise the money to pay for rehab out of pocket for the first couple months until the insurance starts.  He is starting to get stiff and losing a lot of muscle , we are losing valuable time towards his rehabilitation.  We need help getting him into a rehab center so he can get on the path to a speedy recovery.  We aren't exactly sure how much the rehab will cost, but the hospital said it will be more than a skilled nursing facility which runs about 8k a month. Anything helps. Thank you.  Please continue to share.
