Handicapped addition

We have a very special 8 year old daughter who is 100% dependent on others. Emerson was born with a mitochondrial disorder and began having seizures at 6 weeks old. She had as many as 100 seizures per day before going on the ketogenic diet. She is not able to talk, sit/walk, eat or do any typical of a girl her age. She is absolutely adorable and is happy almost all the time. Unfortunately, we live in a split level house and need to handicap it in order to remain there. This will require a one floor lift/elevator, walk in shower, widening of doorways/hallways, and much needed storage for all of her medical supplies. We love our neighborhood; the school system fully supports Emerson, as well as we have my wife's brothers family and many other wonderful neighbors on the same street to help out with us. Whatever you can do to help us with this endeavor would be greatly appreciated.
Thanks,
The Keohanes
