Turntable dealer/set up percon

A hi- liner can’t teach you how to be a high liner in one trip to extend the fishing analogy... just a bit....

Normally I would ascribe to the 1950
”
rebuild your own transmission “ philosophy but nobody asked the OP about a variety of skills and yes physical acuity needed to wring the best out of a TT setup.

so have it done, learn if you can and or to your comfort level and ability and move on...

hoping the OP enjoys the music !

Please don’t, the MoFi disc ( I have one ) relies on visual alignment of the disc to the pivot point Or plane on the Arm - something not obvious on all designs and the sighting blade is dark wide and a source of lack of precision- use it in a pinch. 
A decent $40 tool but hardly up to snuff for the investment you have already made.
