Why not at the local glass company. Get tempered ?! Tough stuff.
They probably can't groove premade stuff or temper cut glass.
Bigger problem is cutting tempered glass.

And why would you pay $50 an hour (for possibly an hour or more) for
someone to attempt to make something you can buy ready made for less
than half an hour's labour???
When I mentioned local glass companies, I was thinking 1/4" plate
glass, not tempered. For a hoist, it should work, but you're not
readily going to groove it cheaply or easily.

judging from the OPs pics it wasn't tempered in the first place or it
would have broken up far more.
You don't really want tempered glass. What you REALLY want is
borosilicate (or Boron) glass. However, on most cases you can even
get away with a lucite type plastic, at least for a couple years
untill it yellows too much.
But the right part is available at a reasonable cost.
