Easiest cheapest way to fix dent

go to one of those dent wizard places whatever their name is. its easy just reach in pocket to pay when its fixed. i would take grilles and panel off and finness it from the backside personally

or eastwood has this Eastwood Paintless Dent Repair and Removal Kit
I don't know what those paintless dent repair guys get, but some of the repairs I've seen online are pretty amazing. I would think fixing dents like in your picture, would be child's play for most of those guys.
