well same thing happened to my friend last month. and he was very worried as it seems quite difficult to get rid of dent from side skirt.
But it was damn easy, it took denter only 15-20 mins to remove that dent, but skirt has to be re-painted.
No Need for skirt to be cut, they will drill small holes in that area, and pull that metal sheet outward.
Cost was Rs.2000 , including paint. It was done through Suzuki Franchise Workshop.
Honda would be expensive, but its not a big job, so you can get it done from some normal workshop.
