The company which produces the motors is High End Technology, the motor I think may work for you was the 2W-23. They are the only source for this motor as I have not seen any one else selling them as of yet. These are a fairly high performance motor rated at over 800 watts, not bad for a motor that weighs under 4 ounces.
Here is a link to the page you can order from.

Now as far as the ESCs (speed controllers) I would stick with Castle Creation controllers your going to need something that is going to be able to pump a lot of power into the motors, and have good timing responses. I would look at 80-100 amp types regardless of the manufacture, your going to need something that can make up for your power losses through the hub.
