Visitor's VISA under I-94W

[immihelp]

To whom this may concern:

We have come here in the USA in late March 2007 and have until 01 Jul 2007 to leave the country. We have come here to do business buying classic cars to bring back to New Zealand. As the demand is going great at this time, we would like to stay longer here in the USA to carry on buying. I understand that under the Visa Waiver Program, we are not allowed to request for extension; and therefore will have to leave the country.

If we are to have a break, say travel to any of the nearby countries like Brazil, Canada, or Hawaii; and come back here in the USA, do we get the 90 day stay again?

We hope for your assistance on this matter. Thank you for your time.

With kind regards,

Hawaii is in US, and does not count.
Canada is in North America and does not count.
