This black hat method may work?

1. Buy only one backlink to your website from a related high PR page. The link text must be your most important keyword.
2. Visit that high PR article every day from hundreds of private proxyes with different browsers and click to that link, and stay in your website for a few minutes.
3. Hire some people to visit the article and click your link everyday, so it will be natural to Google's eyes.

Do it again and again until Google will increase your ranking.

I think it doesn't really matter how many backlinks you have. The only thing is matter that how many real people click to that link. If nobody click your backlink Google will know that's just a spam.

If it would be that simple ...

Don't think that's how it works man,Google is smarter than you think,And that would be time consuming.And for your site to get visits from nowhere would look spammy to Google.
