ambs is right with the CGI tip. If you take a look at merlyn's new book Perls of Wisdom there's a section about calling web pages using CGI so you can limit linking directly to a subpage on your site. That should be enough to get you started. Plus the rest of the book is a great read. :)
Useless trivia: In the 2004 Las Vegas phone book there are approximately 28 pages of ads for massage, but almost 200 for lawyers.
