Where to find exposure for my 4 year old daughter?

Don't do it. She's 4, she'll do anything to get approval from Mom and Dad and putting her in a business rife with deception, lack of concern or respect for children as human beings, and an exhausting schedule of auditions where approval comes in approx. only 1 out of every 300 audition attempts for professional, established adult working SAG members is something you want. What does she want? Besides, I've never met a 4 year old who didn't have a lively free spirited personality. Don't be an idiot.
