Need someone to help out with the house cleaning and some chores'

I will be 67 in November and my ex husband is 76. We can't get things done like we use to. I don't know if I can afford this until I talk with someone. But I have a bad back and can do a little at a time, so I just can't keep up. My ex doesn't help much but he's good staying out of the way. If someone will call me and just give me some information so I can know if I can afford to do this, because I don't think he will help pay for any of this.
