There's zero difference in the amount of time involved to drill 2 (incorrect) holes for the emblems and to place the (incorrect) stripe lines as it does to do it correctly. Those kind of mistakes are simply careless and uncalled for mistakes. Specially when there's thousands of pics out there to view off the net.
PULLING THE TRIGGER ON THE DRILL AND PIERCING THE METAL TAKES THE SAME AMOUNT OF TIME...
There actually is a good bit more time involved in correctly laying everything out and checking and rechecking.
Researching, checking, and double checking then laying it out, then checking again.
Checking with the light bezel installed is KEY to getting the proper alignment.
After painting the body color then install the emblem and use 1/4" masking to ensure the stripes are spaced correctly and aligned with the emblem edges.
Dab some ink on the pins hold the emblem up make a couple of marks with the pins and drill some holes...
I'd say about 2-3 hours difference for the emblems and stripes...
FWIW if paying a shop it would be money well spent.
