Anyone seeking careers in tech?

I was just wondering if anyone could provide some feedback to me.  I work for a company that provides information utilized by most placement services and staffing firms in the high tech industry in California.  These firms charge people up to 35% of their first year's income for successful placement.  People need these agencies because these companies are NOT easy to find and/or contact!  Here's my question....why would those seeking tech careers not respond to an ad that allows them to obtain the same information for only 80 bucks!?
We have been doing this for over 10 years and we're extremely popular at career fairs, high tech fests, and college campuses.  Any feedback would be great! (I've even offered to give NETSMOG folks 10% off this already nominally priced information service!)
