For a sink I would make a plywood router template and go that route, but of course after practice similar to a sink cut-out first, even if it’s smaller scale but still a square or rectangle with some inside corners. I would also run one or two shop vacs to contain the dust as much as possible, one under the sink hole to draw everything down (have the doors closed on the hose and tape up the door gaps) and perhaps a helper manning another vac close to the router bit.
Barring that I’d just look for a well-established shop that’s been around town for a while and is a factory dealer.
The composite sinks I’ve seen lately have all been OK but I recall an early generation one something like 16 years back where the entire bottom of the sink cracked and detached from the rapid thermal expansion when the homeowner emptied his pot of hot pasta water into it. He called us to replace it with a stainless steel sink (it barely had coverage of the crappily cut hole in the counter and some fine-tuned tweaking was necessary. Some silicone had to cover tiny slivers of gaps from the wandering perimeter of the cut out
as we had the largest sink available at the time to fit the hole).

I've talked to a few of the countertop groups, and pretty much get the same answer ... because of liability issues , they'll only do their own product.
I considered doing it myself, as you say, looking on the old interweb ... it appears pretty much doable, but the big concern, as with the big companies. is the " what if's "
I did get a referral from one of the members here , so ill be calling that on Mon or Tues .
