Radiator repairs in South West?

My dad had a little whoopsie on the way to Weston bike night this evening and rear ended my bike at a roundabout. I Managed to stay upright and luckily there is no actual damage to my bike however...his rad (triumph rocket III so its freaking HUUGE) caught my rear wheel, pushed it back in towards the tank and has put a hole in it, coolant was really pouring out so i guess its a fairly big hole.

Google has found a genuine replacement for £510, and thats not including any of the caps/covers/cowls that need replacing or postage!

Ive found a place in london that will repair/make a copy for £220 +P&P but would like to find somewhere local if i can.....

So does anybody know anywhere ideally bristol or bath but will travel a little bit that will repair radiators, or alternatively make a new one!?

P.S - ill take some photos of the damage when i get the rad off the bike tomorrow to see what the damage actually is)
