Theres only one answer is... How much is your budget and willing to spend. You should at least start submitting to the directories now till before the update. Changes would be done and the pricing would be different. Try The New Upcoming Strongest Directories. Most of them have good prices and are presumed good contenders. As for DMOZ Submit and Forget. That is the only advice I can give you.
The amount you spend on directories depends on whether you submit to Free or Paid Directories, and to the quality of links you are targeting DMOZ have you got a calendar as you will need it because you will have to wait some time But we consider there is no finite timeline for submissions as we consider it a daily ongoing continuos process Spend to your budget, create some revenue, then re-invest in submissions
Well DMOZ will take forever or about $250-$300 to a corrupt editor Just submit to free directories and you'll get indexed properly. Don't waste time submitting to search engines.
Either do it yourself or pay there are a lot of good submission folks hereon DP most with excellent rep
I'm having problems with submission company not submitting in a proper categories in my free directories and therefore I just delete them without a review, So choose your submission company wisely. I've notice that a popular submitter guy often violates my rules by submitting to Top categories which is a No-No.
