I completely agree, fiberglass work is not all that tough and the supplies are easy to find at auto parts stores, marine supply stores, or online. Lots of videos of how to do it. Glassing in aluminum strips here and there can really strengthen things like this, and using glass fabric for the repair will make it even stronger than the chop glass original material was.
Of the $500 quote, it may have included over $300 for color match and paint, or a bunch of labor to remove the step, as the glass work should not be that much.
