Does anyone know of any istance programs for wheelchair lifts?

My niece was very sick as a baby and had several strokes because of this. This has impaired her ability to walk. She is having another surgery that will further delay her therapy because of recovery time. So, she will have to remain in chair. It takes the whole family to care for her and supply her needs. We are almost financially and emotionally depleted. In the area we live in if you don't get a fancy lawyer to advocate you miss out on alot of things like modifications for transportation. I've gone to every agency in the area that I know of. The most they have to offer is a wheelchair ramp. This is no good for a power chair. The vehicle has to be completely modified. I know there are services out there for this. Does anyone know of any? Please help. She deserves to get around like everyone else who walks.
