Why not join and post to some Wiki Sites. As of this posting, Jan 2010 The top 20 sites shown below let you set up your own wiki pages.
You could also use a service that does this already but you would pay between $400 - $1,000 for a one time post on each wiki.
This would get you 20+ entries of permanent back-links that would easily generate over 600 links once indexed.
I took the time to register with each wiki today, it took several hours.
Once you register, then it's time to set up your wiki on each one. If you only have 1 domain you are better off outsourcing this project. If you run dozens of domains or do SEO or Internet Marketing for a living it would be worth including this in your portfolio of tools.
Feel free to post your Wiki URL's back here when done. Don't forget your proper in anchor texts to link back to your Wiki's. With new Google updates be sure not to over use your anchor keywords. Natural links are best. Click here to quickly post to 500 Wiki sites.
