Babysitter/ Petsitter

How do I find people that will let me babysit/ pet sit for them... I’m 17 and I don’t have a car but I love kids and I used to babysit for my sister but she would only pay me 5$ a day per kid (2) then they started daycare and school and now I don’t know anyone that will let me watch their kids. I live in Trinity/Sophia/Archdale NC
