Keyboard Key modifier file/program for Mac

We have a new keyboard which is Mac and PC compatible. However the keyboard is currently set up so the standard Mac CMD key is currently in a different position to that of a standard Mac keyboard. (two to the left.) What we require is either a small file that our customers can copy onto their mac or a small program which allows users to pick off this key and move it into the new position and run a program so the two keys are then swapped around in the system preferences. Please see photo for example of current position and new position. Thanks Mark
