Buzz generation/ Diggs/ Traffic

Hello, I will be going live with a new Web 2.0 application soon and currently running a blog to generate some buzz and make users preregister for the service. In order to increase visibility, I would like to get one of my next blog posts on the front page of Digg. The article will not be advertising only but with interesting content (really) and well-written, so we are starting from a good position. Therefore I am looking for people who could help me with that. If interested, please describe how you would do it (without running the risk of getting banned on Digg) and where you have succeeded with it already. I would very much like to agree on a payment that highly depends on the outcome (e.g. X as basis and +Y if story gets onto Diggs front page). I am also interested in other proposals for increasing the blogs visibility (link building etc.) so if you have experience with that we can talk about this as well. Thank you!
