Accounting aside, just wanted to mention that most of these barriers are whether you have a US-residence credit card, or bank account, not so much about where you or the company
actually live.
Not sure it's worth incorporating a company (which may involve foreign ownership accounting hassles) to handle it.
You might want to try to get a bank account or CC in the states, and fund it personally, and just not get the business deduction for it. I did that with Amazon's services, before they accepted credit cards.
Hope that helps and good luck with it.
