I've always thought it would be good to setup a LinkedIn type platform that let's the user 1) put a white list of contacts or 2) A price to contact. If your not on the whitelist any contact gets a response of "please pay X" for emails to get through. People can place their own value on their time and advertisers can decide if this is worth it. Also you could add a call feature where if a recruiter/sales person wants to schedule a call they can (via forwarded number to keep anonymity) at the agreed rate.
