Align a form in CSS

I am a designer who has recently started teaching myself CSS so I can develop my website. I have figured almost everything out except for one thing. I have an email subscription form that I can't get to align correctly. Here is the website as is: [login to view URL] Here is a jpg mockup of what I want it to look like: [login to view URL] The form to the right of the "SUBSCRIBE FOR EMAIL UPDATES »" is the issue. I attached the mockup, HTML content and CSS file. The CSS and HTML content files are attached.
