Have a weekly online live lecture for members. Membership should be a low fee to have as many members as possible. Additional revenues from a commission from lecturers sales. Members can access replays and synopsized replays with just the main points (and the pitch.) This is less about the person and more about the actual help they provide each week.
Get live help in your ear when (after training) they start working in their new job (sales, services etc.)
Have a concealed in-ear piece transmitting what they hear to the live-helper and receiving real-time help from him.
