Professional Services can be purchased from Vizrt resellers. Basically you are getting blocks of time which can be used for a variety of things like training, workflow development or like in the case above the manual configuration of 3Play systems to use the Remote Control Surface tool. The amount of Professional Services time is sold in blocks, and the minimum amount of time would be enough to get the Remote Control tool working.
Central Control might be another possibility, but I do not believe that the 3Play 440 CS (the one with keypad) is supported by Central Control (they do support the older 3Play CS units).
