Elderly night time home aide

Looking for a female night time home aide for my elderly mother. My mom lives alone. She needs someone to be there at night to make sure she is safe and move around in her apartment safely. She had strokes which makes her walk clumsily, otherwise, she is healthy and mentally sound. Home aide will spend 12 hours per night (eg. 8PM to 8AM) in the apartment with her. Home aide will be free to do anything and rest/ sleep on our new sofa bed whenever she wants. My mom does not need to be engaged at all times. Ideally someone works or study nearby such as Queens College student.
