Tracking operation hours and amp draw for a motor control system.

I need to design a box that monitors the current draw for a DC motor control system. I need to reccord the progress of the current draw over time. In addition I need to reccord the amount of hours the motor control system is in opperation. AND if that wasn't enough I need to develop a box that monitors multiple motor control systems simultaniously. That monitoring box must link with a PC that interprets the information utilizing a visual basic software program... aaaarg. This will enable a single technician to easily track the progress and status of the individual systems. Thus he/she can perform the necisary preventative maintenance when it is indicated by hours or amp draw for an individual system.
