Google's John Mueller posted a response in a Google Webmaster Help thread responding to someone asking if they need their keyword in their domain name.
In short, John said no, you can rank fine without having a keyword in your domain name. Heck, my company, RustyBrick, doesn't have our money keyword in our domain name. Not that I rank that well for our money keywords. :)
That being said, John Mueller said it isn't needed.
You don't need your keywords in your domain name. Websites without them in there rank just fine. Instead of focusing on that specific keyword, I'd recommend spending the time to make your site the absolute best of its kind.
