Aluminium welding work - who/where?

[crankedup]

I'm in need of somebody to weld some hollow aluminium balls to the ends of my aluminium caravan gutters.
The gutters are tearing my caravan cover therefore I think the rounded ball ends will stop this expensive and annoying occurrence. I will drill a drain hole in each ball of course.

Can any one give me a lead please? I'm in Bury St Edmunds.

Thanks chaps, just waiting for my balls to arrive in the post hope the welding can be done.
