I would take it to a body shop that you have used or know their rep. Let them fix it and be done. Or.....like you said....a fiberglas patch and DIY.....little touch up paint when you are done.

I can't imagine an "amateur" non-professional fiberglass mechanic to make anything other than a cobbled up mess if they try to patch this with fiberglass cloth themselves. the only possibility is using white bondo and sand and paint to match.
can you patch it/ paint it/ and slap a reflector over it?
