Should I add keywords to my domain name to get listed hire up in the search engines?

I'm starting an advertising company called "Goodidea". I was thinking of buying two domains: goodidea.com and goodideaadvertisingagency.com. Then I was going to 301 redirect goodidea.com to goodideaadvertisingagency.com. I would then optimize goodideaadvertisingagency.com for SEO. Even though my logo and text on my web pages would say goodidea.com the domain name would say goodideaadvertisingagency.com. Would doing this get me listed hire up on the search engines for the term "advertising agency"?
