Ok a suggestion for You,
Contact these people,

They will act as Your US agent, use Your EU address as your permenant one, they will forward all recieved docs relating to Your new company to You anywhere
Next, once incorporated contact the IRS, and request Form SS4, once You fill this out and fax it back to them, You will be issued a company tax id number
Lastly, get on a plane with all Your paperwork, and hit any main bank in the US and You will have a business account with Your own company Visa card
