I would not 301 redirect because it passes link juice, it will also pass the link juice from sites that have nothing to do with your phrases. What I would recommend is starting a new site. Manually check all your old backlinks. Find the backlinks that are authoritative and relevant to your topic (usually sites that have your keyword phrases in them), and contact them. Your email should be: Dear____ , we have moved our site to a new location can you please edit our link?
I love giving value.. The more value I give the more value I get (aka karma, and yes I am a hippie)
When you contact these sites webmaster you can check their sites in a broken link checker tool or find something to help them improve. If you cannot find something to improve at least be somewhat entertaining. Remember webmasters are people too!
