Found a guy halfway across the world, but we did Skype screen-sharing so we could talk and I could watch his screen.

Didn't cost much. The key was how I asked. I just made it a criteria of the job when I posted/announced it. "Looking for someone to program while I watch and ask questions."

I know he really enjoyed it. Said it was much more rewarding than the usual coding in solitude, not knowing if the client is really appreciating the effort.
