Hm, it seems to really be online. At some UK banks there was a online form but the second step was to go into one of their offices.

here: "To apply online, you must be 18 or older, a U.S. citizen or resident alien, and have a U.S. address. You also need a Social Security Number and U.S. driver's license or state-issued ID."

will check about business accounts.

This only applies to individuals. Business accounts don't have this option.

I don't see anything like business accounts there unfortunately.
