The quarter bumper appears to be available for around the £50 mark,

The panel damage appears to be quite deep as the side panel is distorted, but all is repairable by a body shop. With paint, which won't be that easy to blend in, it could be, at a guess £1k.
Try a few body shops and get some estimates.
