Find a talented Junior developer which is able to think in your in presence (not stunted by your presence) and out spoken enough to disagree while you stand them character wise and take them under your wing. Mentor them as far as you think you can be effective mentoring them. Then let them grow on their own and after some break pick the next candidate.
Edit: Oh i see you are already doing that. Different suggestions: network with fellow professionals and contribute to a trade publication.
