A possible source is Ace Metal Spinning in Los Angeles, they have a variety
of forms. I seem to recall that a 1 meter sphere would set you back in the
area of $400-500. As you get bigger, not only is there a problem of
actually manipulating the huge sheet of metal being spun, but just getting
it in the first place. Aluminum comes in 4 or 5 foot wide sheets.
For the truly adventurous, Lindsay Publications has a book on metal
spinning for a few dollars. I can't find my catalog, but call them up and
get the metalworking books catalog. It should be in there.
