Here is a tour of the SpaceX factory, complements of Wired, with nice photographs and concise commentary. Here is their stated philosophy (my emphasis):

Started in 2002 by PayPal founder Elon Musk, SpaceX (short for Space Exploration Technologies Corporation) brings a startup mentality to launching rockets into orbit, which until recently was almost exclusively government turf. The hope is that minimal bureaucracy, innovation and in-house manufacturing and testing can be used to put payloads into space at roughly one-tenth the cost of traditional methods.

If you want to enter the space business, I suggest starting something like PayPal and getting bought out by eBay. (Or start something like eBay; that works, too.)

SpaceX will have a test flight of their larger craft (Falcon 9) and hope to have a commercial payload by the end of 2009.
