Putting a hole in a keg...

This is a bit of a long shot, but is there a benevolent, bribable brewer somewhere in Auckland with the means to help me get a 32mm hole in the side of SS keg? I'm wanting to put an element into my still boiler, gas prices are getting me down... I've fairly well buggered my own cheapy hole saw, which to be fair I expected, was just hoping I'd get one cut out of it first. I was disappointed.

Help? :)
