Nasty.
The paint doesn't look damaged which kinda rules out a screwdriver imo. If you hammered one in THAT hard to do that it'd scrape paint, slip a bit, or go through... it looks like a lot of force but a rather blunt tip to me. It's impossible to say vandal without knowing really. Someone might have dropped something long onto the car?! Who knows...
Anyway, as said, if the panel is a 'write off' no harm in trying to sort it first for much less £££...
As for the boot, same again, but I think that will be harder near the panel edge.
I'd try get em banged out first and go from there. Only step up when you need to or are not happy with the result.
My wife just had some dents removed by a really good dent guy (the Ford garage used the same guy for 7 years or so), and we were amazed at what he achieved with a dent on a swage line and another subtle dent underneath it!
