We don't provide site specific advice here, which is why you were asked not to provide a URL.
If your directory is focused on some sector, suggest it to the sector's category here - but not until it's content is significant.
If it's very general, you'll need around 100,000 listings before we'd be interested in adding it.
Always, when evaluating a website, we ask whether or not listing it would enhance ODP's value to the surfer. If it wouldn't we don't.
