PHP and Doctrine experience are preferred.
However, though Tom may disagree with me
I do. Past experience has shown that bringing new people up to speed takes a considerable amount of time and effort from the existing dev people. It is an investment. And Tim, you are the rare exception where the investment has paid back massively. You and I both remember quite a few cases where we invested the time and the volunteers just vanished on us. And, before anyone jumps up saying "I would never do that" - all of them said the same thing.
