Looking to understand why sales people are not signing up for my website.

[Serious] Every time I take a recruiter call, I have to explain my background and sales history - time after time, the same conversation and then only to find I am not a fit - frustrating after spending 20 minutes on each call to relive everything I have done. I want recruiters to be able to search for me by what I have done in my career, like a baseball card for an athlete, that way the opportunity is at least somewhat qualified. SO - Over the past year, I have been working on developing a site that will better help recruiters and sales people connect - it's a searchable baseball card for sales people. MY QUESTION - Our website (www.statcard.net) is relative new, but having problems with candidates signing up. Can someone tell me what or why they think they are not signing up? We did start with software sales and about to branch out to medical/pharm - but would someone please tell me why you wouldn't sign up?? Companies want to use this, I just need candidates. Thank you in advance for your time.
