Quite likely you pay a lot more than $10K per new hire.
If you send me a link to your employer's homepage, I'll list it at http://www.warplife.com/jobs/computer/
There is no charge for this service nor will there ever be. I am quite specifically trying to do away with the practice of paying for resume submissions. Consider that a recent study found that the average recruiter "reads" resumes for just six seconds apiece. For that you pay tens of thousands of dollars?
While not strictly necessary it is quite helpful if your employer's site has a "Jobs" or "Careers" page, as well as a "Contact" page.
If your site doesn't explictly say where your office is located, please tell me the city, state or province if any, and country.
You don't need to say that it's from you, specifically, if you wish to remain anonymous. I get submissions from lots of people.
