I would imagine there are no short-cuts? Just the usual hard work with great content and level of back-links?
Google PR isn't that predictable and there is so many variables that no one will tell what to do with your website to increase PR. But as far as I am concerned then links form high quality website will help the most, at least that helps my websites to increase PR and ranking in Google results
You need to entice other content authors in your niche to link to your website. Otherwise, you have to pay an SEO specialist to do the hard work for you.
As much as possible, publish a daily post on your websites and do social bookmarking and share it on social networking websites.
I personally advice to you that, increase traffic for your URL, and do Off page optimization, So you will be get back links and also will get increase PR for you site.
