looking for Wolf 30-inch range and oven with 18-inch cooktop grill and an overall outside venting range hood. Need dimensions, cost photo, Stainless steel matt finish

That size? Huge, expensive.

Look at ModernAire, VentAHood, Bluestar and other similar companies. They all can build you 54+" (48" plus required overhang) hoods, and they can install sufficiently powerful fans. But it won't be cheap. And you almost certainly will need a make up air system for a hood size.

Read the archives. There are lots of detailed discussions on what you need if you want your hood to be more than a glorified noise maker.

18-40K for that depending on appliance choices and makeup Air requirements. All to asphyxiate yourself indoors.

Grill outside.
