Paintless dent repair?

[Funkstar De Luxe]

Hello all!

Some cretin has opened their door against my car and I need a dent removed (pic below).

Can anyone recommend me a dent repair place or guy who will do a decent job? The last guy I used left large scratches all over everything - I think his magnetic light thing must have been dirty

I'm near Coalville / Leicester but can drive a wee bit
