Amazon said Monday it has received 238 pitches from places across North America vying to be home to its second headquarters.

It's the prize of a lifetime -- a $5 billion investment creating 50,000 well-paid jobs that everyone wants, but only one city will get.

"We received 238 proposals from across North America for #HQ2," the Seattle-based internet colossus said in a post from its official Twitter account.

"The team is excited to review each of them!"

From East to West and North to South, metropolises across the United States are locked in a frenzied bidding war, desperate to woo Amazon into favoring them as the site of the e-commerce giant's second headquarters.

Proposals were also reported to have come from Canada and Mexico.

From $7 billion in tax breaks in Newark, New Jersey -- 50 years ago aflame in deadly race riots -- to a giant cactus shipped inter-state from Tucson in Arizona, bids ranged from the extremely ambitious to the silly before the deadline for submissions recently passed.

The e-commerce giant announced last month that it planned to invest more than $5 billion in opening Amazon HQ2, a second company headquarters in North America that would also create tens of thousands of spin-off jobs.

"We expect HQ2 to be a full equal to our Seattle headquarters," promised Amazon founder Jeff Bezos, America's second richest billionaire worth $85.8 billion.

The unusual announcement unleashed competitive streaks nationwide as some of America's most glittering cities vie with lesser-known backwaters looking to exit oblivion.

In addition to direct hiring and investment, Amazon expected construction and operation of HQ2 to create tens of thousands of additional jobs.

Amazon said in an online post that it is making the selection of its second headquarters a public process because "we want to find a city that is excited to work with us."

It has expressed a preference for places with more than one million people, a business-friendly environment and urban or suburban locations able to attract and retain strong technical talent.

A study commissioned by World Business Chicago claimed that in 17 years, HQ2 would generate $341 billion in total spending, including $71 billion in salaries.
