Sitter Job in Charlotte, North Carolina

My son is 8yr and is a type one diabetic, he uses insulin pens. As of right now I'm mainly working second shift with a company at the airport, however, I am working on getting a first shift job. My son uses insulin pens, and is able to give his own shots and check his blood. All he needs is for someone to tell him how many units to give himself (I will give you everything and explain how to do this), and remind him to check his blood before meals. Until I'm able to get a first shift job, he will need to be picked up from school at 3:00pm. So I would prefer someone that lives at or near 28212 zip code. I'm a single mom, so please be understanding if I'm unable to hire you due to price. And please be reliable, I've had too many sitters quit on me. Caring for my son is a lot easier than most people think. I would prefer someone who is familiar with diabetes, especially type one. However, it's not a must.
