Surely enough, if you look at the site's introduction, they are all amateurs indeed.

Real Street Angels is a POV (Point of View) website all about stylish and cute amateur girls that we see on (and pick up off of) the street."
Meaning you most likely won't find this girl anywhere else except this website. Sorry mate.
