Need Info On The Best Rehab Facility

My sister is in need of an in house excellent rehab center. We live in Michigan and we are willing to travel anywhere in Michigan. We are desperate. She is home right now and she is getting rehab at home but they are all saying she needs in house extensive rehab. The rehab center she was in before was useless. It was called Health source in Saginaw. She was diagnosed with GBS in March of 2010 and she acquired C-Diff infection about 3 months ago and had to have her Colon removed. Their insurance ran out so her husband brought her home. He cannot keep up with the rehab. The therapists come to her house 3 days a week but the aggressive rehab she needs they cannot provide because they do not have the machines to accomplish this. Her insurance has been reinstated and her husband is willing to pay any extra that it would cost.
any help anyone can provide would be greatly appreciated. The sooner we get this info the better.
Thanks to all and God Bless
