Start Commenting on Others Blog. Dofollow or Nofollow, don't matter.
If you are VERY particular about Dofollow blogs than use this software to find dofollow blogs.
TIp - DO NOT user automated blog commenting softwares which claims "Great results" since the only result you will get is your site getting banned from Google.
If you don't have time than you can hire a Freelancer and pay him like $25 to make nice sensible comments.
Tip 2- Start commenting on A List Bloggers, because sensible Comment + A list Blog - decent traffic. Make sure, you keep the relevancy, dropping a mortgage link on a designing block is not very cool. And putting "Buy Cheap links" on this blog won't help either. :)
