Found this fantastic list of free web directories compiled by SEOCompany.ca.
I really like idea of displaying the Google PageRank value, Alexa traffic ranking and Google, Yahoo and Live link popularity of each web directory.
Using this list, you can start submitting today and in a couple of months your web page PR will definitely improve. Also since many of these directories have high Alexa traffic ranking, you may also get more targeted traffic to your web pages.
If you do not have the time but have some spare cash, you can visit forum such as forums.digitalpoint.com
Go to the section:
Digital Point Forums > Business > Buy, Sell or Trade > Services
and you will be able to find manual web directories services at affordable price.
