Alum welders - not for bike

I'm after someone who can weld up an alum box/container that will hold aprox 200 ltrs lets say 400 x 400 x 800mm or an even bigger one with 3 compartments that will hold 200ltrs ish each, at about 900 x 500 x 1500mm. I'll need some bsp sockets welded into them as well.

Cheers
