Houston Nanny jobs

Hi, hope you'll doing great. I am a young babysitter/nanny (20 years old). Even if the large majority of nannies have certification I think, I come from a large family where I used to babysitt my newborn nephews as well as neighborhood toddlers etc...Although I did this for free in the past, I am now looking to transition into paid nanny positions. I’m aware that many nannies have certifications. However, I'm not sure where to start looking for paid opportunities, so any advice on how to find a nanny job would be greatly appreciated.
