I didn't recognize the demand until I began hearing from independent consultants asking for advice or talking about abandoning their business because they wanted to focus n coding and not marketing and their 'brand'. They liked the work they did, but not the work of running a business. Likewise, engineers in full time perm jobs were asking for career advice on a regular basis - not just negotiation, but whether to stay hands on vs manage, whether to get a certification, to take pay cuts for a better tech environment, etc. The answers depend on the candidate's situation, but I became a trusted advisor to many. I gave this expertise away, and I think a model exists where an agent would do these things and more. May sound 'frothy' now, but its a new idea.
