These tend to be hugely coveted jobs (often more so then Broadway gigs) because of the money and the relatively little time commitment (i had a friend do 3 weeks in Milan at 5,000 a week - but 3 months planning). The best is do research into those production companies the produce them in the area you are now, and get your feet wet - they aren't for everyone. Also, this is one of those areas where having a tie with an agent or agency helps, and there are production groups (directors, choreographers, stage mangers, designers) that travel in packs.
But again, almost all regions have one or two of production companies that do industrials / corporate events.
