Buried in http://www.nytimes.com/2012/09/15/health/policy/california-tries-to-lead-way-on-health-law.html is the cost of building the Web site where some currently uninsured Californians will shop for health insurance: “Most of the money is committed to consultants, including Accenture, which has a $327 million contract to build and support the initial operation of the enrollment portal.”
One of the amazing things about Obamacare is that it preserves the state-by-state restrictions on competition among insurance companies. So instead of the government building a single $327 million web site that all Americans can use, each of the 50 state governments gets to build its own $327 million web site (though of course, from a technical point of view, there is no reason that a single web site could not offer 50 different views of the same database, each view customized to show options available in a particular state).
[Compare to the Google search engine company, built by two Stanford graduate students in their spare time. Google’s expansion was funded by $100,000 in August 1998 and $25 million in June 1999 (Wikipedia). Amazon.com was funded by Jeff Bezos’s parents and then with a $1 million second round (source).]
