Dofollow backlinks are the ones that count in google, meaning they will boost your ranking.

Heres what to do:

go to http://ask.sdglassrestoration.com/ (its a Q&A support forum for glass restoration and glass graffiti removal)

If this is an area of interest to you (it's very nice ad on service) and you have any questions about getting into the biz, or if you are already doing it and want to share your knowledge then head over and participate!

You'll learn alot about a cool service and if you include your URL when commenting, and use your keywords for your name (Just like your signatures on here).  In other words your name will be your anchor text.

Enjoy,

Doug

http://window-replacement-alternatives.com/ that would be so awesome, THANKS!
