Baby sitter / nanny

Hello mommies.... I’m a mom of a one year old and I’d like to become a nanny or a full time baby sitter . I live in Florida. I was wondering what qualifications would I have to get ? I have plenty experience with babies and kids from my own family. I wanna get started with this . Any advice or information is welcomed! I want to post ads on fb about anyone who needs a reliable and trustworthy baby sitter but how could I convince them? And how can I become certified? I googled it but still couldn’t find a appropriate answer or information
