Directory submission is a daily chore and becoming less and less important everyday. Do a search for 'submit site' or 'directory submission' or 'submit URL' and see what pops up. Do a search for your own keywords and see if any directories turn up in the SERPs.

Other things to consider are newsletters, blogs, rss feed and other social networking sources. And the more competitive the market the more difficult it is to get noticed.
