Where is your neutral to bring it to 120V? This is split phase. L1, L2, Neutral and ground.

The problem Rex, is that you need much larger conductors for lower voltages in long runs. It is more economical to run the higher voltages from L1 and L2 (240V) of your split phase service, drop a transformer at the end and that will provide you with the neutral to drop down to 120V.
