I just wanted to make a recommendation for a contractor we've used for the last few months. His name is Walter McGinnis, and we are winding his contract down at the end of the month as we enter validated learning phase and conserve cash (otherwise we'd still have him on board! :D). We're a Rails 3.x and Ember.js shop, so if your needs happen to intersect with that, you really should check him out! Although he lives in New Zealand, he was very responsive and shifted his schedule to accommodate ours.
Drop him a line!
