If you have the ability to design Wordpress themes your should be able to get 100’s of backlinks easily.  Remember to design a theme around your business niche.  If you have a hunting website design a hunter’s theme.  Within a year you will have 100’s of text links that you control the anchor text to, used on relevant websites.  What could be better for any webmaster.

Once you design the theme make sure you promote it in the right places.  Start with the Wordpress website.  When submitting the themes to different websites make sure you use keyword rich tags.
