I'm trying to build a panagraph and then make it travel on a track. I'm willing to hire someone to do this. Thanks.

What's a panagraph?
-
I think he meant 'pantograph' [or as it's sometimes spelled 'pantagraph'].
It's the device consisting of two parallel, hinged, double-diamond lattice-frames, that transfer current from an overhead wire to a vehicle, such as a tram/trolley-car or electric-locomotive - the sprung action ensures that the contacts are always touching the overhead wires even when their level varies relative to the vehicle's roof-top.
A 'pantograph'/'pantagraph' is also a similar looking device that's used to copy drawing by hand - one end of it holds a pen/pencil onto a blank sheet of paper and the other end has a pointer that you hold, with which you trace over the lines in an adjacent drawing; the movement of the pointer is mimicked in the pen/pencil and lines are drawn on the blank-sheet: if you change the hinge-points in its diamond lattice then the copy is scaled up/down in size as the movements are exaggerated or reduced - that's a VERY early form of copying, much like the much easier 'photocopy' or scan/PC methods of enlargement/reduction!
