PS... Many years ago, I thought of creating a directory and search engine specifically for my site's core subject. I obtained a script, installed it, worked for months getting it going and one day it stopped working. The script provider simply went out of business and I ended up with nothing.
Now that's bad enough, but the worst part is that my site was listed by some unknown entity as a search engine where people could add their links. 13 years later, that's still in search results and I am swamped daily with thousands of requests and get tons of junkmail.
My advice, therefore, is to be very, very careful and to think long term when it comes to the directory concept. You won't receive links from normal companies, but from every illicit, illegal and improper site out there, all of which are spammers.
