Just collected my wheel from the company mentioned by jv (
http://www.wheelrefurbishing.com) and I'm very impressed with the results

Went with them as they were the only one to reply to my emails.
It's not the wheel in my first post but a spare that I have that had also been kerbed. It was easier to leave this wheel as it hasn't got a tyre fitted. I was hoping they would be able to swap the tyre from the damaged wheel onto this one but they were too busy so I will go back in a week or so once I get the tyres swapped over.
Anyway, here's a couple of pics:
Before:

After:

Cost a total of £55

Just need to find somewhere that will be able to change the tyre over without damaging it now!
