How much do you usually spend to clean an industrial pizza oven, and the respective vent hood?

I am just looking for an estimate, the one specifically I am talking about a middleby marshall conveyor oven. It has two levels, two conveyors, and is about 60" track length I would say. I've seen everything from $300 to $2500 and I would ideally like a closer average than that. Please and Thank you! submitted by /u/Max6201
