There are scant few specific "directories" in my niche.

DOn't just look for directories of vendors in your niche, though that is one avenue. i.e. generalize what you sell and go looking for directories that are somewhat more general in nature but still specific to the class of items.

Research directories that touch your niche in any way. From your vendors, to your products, to your product classes, to who your clients are, to your region.

So if you sold tires to volvo owners, you would look for rubber directories, tire directories, car directories, and volvo directories. So while there may be few directories of 'tire dealers for volvo owners' unless you go into general directories, there's a good chance that you'll find directories related to volvo. And per a previous discussion we've had, I'd suggest that reaching out to the 'volvo' community for you is where you should be getting your links.
