I will have to stop working in order to do this, He requires help with ,baths, meds, and urostomy bag changes. l do all his laundry, meals, Dr's appt's. I also pay for his food, cell phone ,internet,water,garbage,and ele for his uninsulated 35 ft rv that is parked in my back yard all year long. I also clean his rv and have to take it out to dump tanks every 4 to 6 weeks. I do this all year with no help from siblings and have no vacation time,sick leave, health ins.401k ect. Cost to me is around $15 per hour if I need to be gone for more than 3 to 4 hrs. Plus I will have tax's to pay on any money I do take for caring for him,
Think about what it would cost for him to be in a NH.
Private full time care, here, in AZ., with a staff of 3 trained care takers in $11,000 per month. As you have already said, a sitter is $15.00 per hour. It would be reasonable for you to charge more than that.
