try a PDR guy if they cant fix it they normally dont charge
and my dent was almost identicle to this with similarly bad dent and i would say it was repaired to 95% all you could see was where the highspots had been tapped and like i said, my dent had a crease.
worth a try,
As i have already said, had this work done on my car and watched it being done, so unless you guys saying it wont happen are PDRers or have had it done, i suspect its at least worth him getting it looked at.
(sorry you have caught me on a bad day lol)
