I ran a jobs site and couldn't figure out how to monetize it for the longest time until I ran across ResumeRobin.com Affiliate Programom
This program converts absolutely beautiful and has monthly rebills. Customers frequently stay for several months and I get checks for all those months.
It's a great affiliate program ... lately I've been pulling over $25k/month on it, my best month was $38,000/month ... if you have any kind of website, join that affiliate program ...
