Housekeeper Needed

I am having back surgery, and while I don't need medical care -- except perhaps transportation to the pharmacy -- I cannot lift anything for one month. I have two cats, and the cat litter must be changed at every visit. I need someone who can lift 10 - 15 pounds -- the cat litter is 10 pounds per package. I am ordering groceries and cat litter to my door, but I need someone to lift boxes and bring them inside. I live in an upstairs condo. There are 17 steps on the stairs. I need to make sure that my caregiver is mobile and can carry 10 - 15 pounds!
