Skype, Google Voice, Yahoo Voice can all provide you with a US phone number. As for the mailing address, that is a little more complicated because of legal concerns. There are many foreign companies that hire "assistants" in the states to maintain post office boxes for them and foreward correspondance to the international address. This is not the best idea I have come across and because of US foreign policy and regulations through the US Patriot Act and the Dept. of Homeland Defense, many US citizens are not willing to participate in this type of dealing, even with legitimate companies. As for remailing services, you could certainly check out this option, I know it used to be a common practice but have not heard of it happening for some time. You could also license a foreign LLC in the states and give some credibility to the prospect when attempting to hire an agent in this country.
