Hi! The movie sounds like a gender swap version of Cinderella, so I searched only for one and this one fits almost exactly like the one your talking about: “Rags” a Nickelodeon tv film. You can read the whole plot on Wikipedia: https://en.m.wikipedia.org/wiki/Rags_(2012_film) and also check it on IMDb: https://m.imdb.com/title/tt1910605/
