I know developers (including myself on a rare occasion - i tend towards custom development) who are doing far better than $70/hour for Drupal development in NYC. Although I don't know many successful developers who explicitly sell themselves as "[Framework] Developers". More often than not, when shooting for a higher rate, it seems to sell better as someone who provides a full solution, which May include specific frameworks if necessary.
