There is only a problem: doing a search on Google with the site:www command, most of these directories have only supplemental pages.....
Could have those listing any value?
Could be a risk to be listed there?
Do linkdomain searches on your main competitors and see which non-free directories get ranked highly; they will be worth some money for your specific topic.
Good luck! W.
