I had 2 smaller dents removed today. The guy done a cracking job.
One thing he did say is, its very hard to remove dents from the bonnet (on a clio) because they are re-enforced at the front, and have the frame around the edge (where your dent is).
Still worth enquiring and getting them to price it up.
The guy charged 60 + VAT per panel, but im based in the south east
