If your content is sorted, then you just need more links.
Of course, what you want are really high quality one way contextual links from really really good authority sites... a few of those will see you on your way. Assuming those are beyond your reach as they almost certainly will be... get slinging:
If you are going to do directory submissions you really want to pay someone for that, or use an automated submitter. If you pay someone you would be looking at around $50 (USD)
Likewise for web 2 stuff, bookmarking, blog posting etc, you want to pay someone or use software like Magic Submitter ($67pm, its cheaper and better than SE Nuke).
Commenting on DO FOLLOW blogs still works contrary to what many would have you believe. This has to be done properly / manually and is expensive in terms of taken, or money paid to a decent commentor. Good comments have to pass human moderation. Auto approve cooments on spammed out sites are not worth using IMO.
The best paid blog posting system around at the moment is BuildMyRank, I have a sizeable review of that on my site and have been using it for a few months. Its effective and less spammy than some of the other methods mentioned.
Reciprocal links are still worth getting if you can arrange some... contrary to what many would have you believe.
Article directories are worth doing if you are using automation, you will need a content spinner and something like Article Demon or Article Marketing robot for that.
Out of all the above, I would start off looking at BuildMyRank, Magic Submitter and an outsourced run on directory submissions. You can get the software for directory submissions yourself, but its a pain to work with and not worth it for promoting one site.
Both BuildMyRank and Magic Submitter are time consuming, and both charge monthly, so I would not get both together, I would start with BMR, get that moving and then look at Magic afterwards, otherwise one or other will be sat idle.
Hope that helps
