This damage can be taken care of by a good PDR technician, it is easily accessible from the underside, no need to replace or even repaint the fender.
I have had worse dents taken out with PDR.
+3...PDR. A good tech should be able to tell you BEFORE working on it whether it can be fixed or not. Which is a no lose deal for you. Should run around $100.PDR specialist.... no more than $150
