The price list you linked looks right, but take a look here: Optical Character Recognition (OCR) - Computer Vision - Azure Cognitive Services | Microsoft Docs
The feature you are looking for is "natural reading order output" and available in the Read API v3.2 preview. It's a brand new feature, so the non-preview API doesn't have it yet. From what I've seen, it performs very well out of the box, so it might be right for you.
Hope that helps
