Seeking Senior Care Provider In Londonderry

I need a non smoking senior care provider with experience for an occasional Saturday or Sunday so I can get out on a weekend day. He is 99 years young, visually impaired ( he uses a cane) and lives with me in my single family home. He is alert, mobile, talkative, and very friendly. He needs a helping hand to guide him when he walks to the bathroom, selecting his clothes, and will need meal prep and help keeping his coffee hot. He does not need help with grooming, dressing, eating or toileting. For 99 he is in amazingly good health and independent.
