You'll need to pull the sink out and get the hole re-punched, check at your local plumbing supply.

I don't know that most/any supplier will have a waste disposal sized hole punch. Generally they only punch in the holes for tapware as the manufacturer pre-punches the sinks for the wastes. You'll also need to recess the area around the waste a few mm to stop water ponding around the raised lip of the waste unit. A sheetmetal fabricator that does a lot of stainless fabrication for commercial kitchens may have the required gear, but I wouldn't want to bet on it. I'd make a few phone calls and if that didn't find anyone I'd be measuring up the existing sink and forking out a couple of hundred for a new one.
