Change the Product Page layout on three OpenCart sites

Here are the layout changes I would like on the product pages of each of three sites: [login to view URL] [login to view URL] and [login to view URL] I have OpenCart 3.0.2 with Journal and my Control Panel is Plesk. (1) Add an additional description field just as in the category pages. It should go below the breadcrumbs and above the product title. It should go all across the page like MaptiteCulotte: [login to view URL] (2) Move additional image thumbnails to the left column as in Amazon. (3) Move the Add to Cart, Add to List, Social Network Share and Compare buttons to the right column as in our Amazon page [login to view URL] Cf. also [login to view URL]%A9mon-Friend-Pikachu/dp/B01C49MHB4/ref=lp_17426286011_1_2?s=toys-and-games&ie=UTF8&qid=1510773279&sr=1-2. Keep the "0 reviews/Write a review" field in the middle column below the options. (4) Move the Product Code and Availability fields below the Options. (5) A Ships By field should be in the middle column below the Availability field as in our Amazon page [login to view URL] Ideally the Ships by field would result from a form in the back end which would say "Usually Ships in X Days " and we fill in a number for X. If that is not possible a blank field where we can add text would be sufficient. Basically I would like our OC layouts to mimic our pages on [login to view URL] [login to view URL] with the sole addition of a description field below the breadcrumbs that fills the page right to left
