How do we find affordable in-home care?

My mother is partially blind with macular degenerate disease, and getting worse. We are trying to keep her in her home, which my brother now owns. Her eyes are getting worse, and the doctor told her she needs to take blood thinners for other problems heart related. She has asthma and is on oxygen all the time. How can we get her affordable assistance in Albuquerque, New Mexico?
