Oh yeah, you don't have a directory for your niche? :).
I have a couple, hand edited, very niche, good quality backlinks, and they're free. I started them primarily just because it's so hard to get links in my niche, it's a place where folks can get at least one free one.
It's also nice because I use the niche for networking. If I'm talking to someone in my niche about SEO, it's one more thing I can throw at them. Hey, have a PR4 link, on the house.
It also lets me see who's doing what in my niche. It's like an email system every time my competitors start an SEO campaign - I get an email telling me they submitted a listing :).
And if I don't like them, I delete their request.
My point is to get creative in how you look for them. Most definately a 'think outside the box' type of search. Combining 'add url', 'submit url', 'add site', 'submit site' or 'submit website' with your keywords in searching might be productive too.
There are lists on the internet of all the different combinations of terms. Such a list was even posted here in the long distance past. Just be careful, even if you find 100's of directories, that doesn't mean it's a good idea to submit to more than about 5 of them.
