I have my own list of directories and I've given that list to one of my freelancers. He will submit six URLs to approximately 1200 directories of the next 3 - 4 weeks.

Each URL that he is submitting to the directories is part of my niche footprint.

I'm not expecting a lot of traffic from these links but they will help with link popularity and it will help to boost the Page Rank of my sites.

The total cost of this will be around $200 or 3 cents per link.
