Where do I find a 220v to 440v 3 phase transformer? Can anyone post me a web address for such?

What exactly are you trying to do? This is a more complex situation than "turn 220 to 440" due to grounding setup or chassis to points voltage differential. The voltage conversion part is something easily done once the requirements and site information are known.
Crossing the 50/60 Hz border is a much more complex issue and may require working with OEM engineer. Disregarding it will most likely wreck the process. The control side issue is more easily managed for Japanese design as Japan uses 50 and 60 Hz depending on region and controls are designed with this in mind and a good chance that mechanical parts for conversion are already available from OEM. (gears and pulleys for synchronous machines, or different pump impellers for direct drive fluid pumps)
Some fluid pumps will require 50->60 or 60->50 conversion for proper functioning if you can't get a replacement impeller or its not feasible economically.
60Hz machine on 50Hz runs at 55% power. 50Hz impeller pumps will run at 175% on 60 Hz and can burn out the motor or overload the power source.
