Home Health Aide Needed

Hi! I am looking for someone to help my parents overnight. My father has Parkinson's and some sciatica pain. He is fairly mobile and doing physical therapy but he sometimes get pain overnight or needs help/supervision going to the bathroom. (he goes on his own but wants someone there to prevent falls). He uses a walker and can get up on his own. My mom has lymphoma and is getting treatment. She is fully mobile and doesn't really need assistance but just needs additional help for my dad. His frequent wake ups keep her awake and she needs rest herself. We want someone in the house during the evenings a few times a week (at less to start) so she can sleep throughout the night.
