Animal Care Needed - Full-time / Part-time

I am exploring care for my two Hollander Lop bunnies. It will require cage cleaning every three to four days along with feeding and time with them. I have a 16 yes 16-year-old terrier pitbull. Shes small. Sleeps a lot and does go on her wee wee pads. I would like to get her outside a couple times during the day. In addition to feeding and water, she has some arthritis medicine that she has no problem taking. When taking outside she must be on a leash. She is going blind and a bit deaf.
