If you're looking to acquire backlinks from high authority domains, then Web 2.0 backlinks should be the first stop.

This service gives you 30 backlinks (web 2.0 profiles) that are unique and different from DA80 and DA90, well established domains.

We incorporate a safe mix of 85% dofollow and 15% nofollow that are in part non-anchored to keep things 'search engine friendly'. The content used is unique and relevant and utilizes anchor texts to give you fully functional contextual backlinks.

The links are 100% Google friendly and wholly free of spam. For best results, you would also need to ensure that you're going after keywords that aren't too competitive, and that the on-page aspects of your site are addressed.
