Links should come from pages with good Page rank.
2. Submit quality original articles to article submission sites. There are many around and
alot of them are free.
3. Make quality comments on a forums or blogs blogs related to your site and insert your link.
4. Seek advice from an SEO specialist that has experience or already has site related to yours.

Quality articles and quality comments has nothing to do with PR.
