Ask HN: How to setup a company in U.S. without being there?

Hi guys, I am working on a startup, and I will need to charge users for my services.

I am in Egypt, and its not possible to have an international merchant account, or in other words, its very expensive..

So I would like to know, how can I setup a tax ID and EIN or whatever, so I can make a merchant account based in U.S.?

Is it possible to do that without having to be physically in the U.S.? Are there any companies that help do that?

Thanks so much in advance.
