You need a corporate resolution authorizing you to perform financial actions on behalf of the company, and this needs signed by officers of the company (which may also be you) and stamped with the company seal. There are plenty of examples online.

Take this, along with copies of your articles of incorporation and government issued photo id, to a bank of your choice and you're all set. To speed things up you may want to call ahead and make an appointment with whoever deals with new business accounts at the branch.
