Wordpress Theme Customization

We are looking to rework the product page layout style #2 for our site. This layout can be seen here at our site ([login to view URL]) and here at the original theme site demo ([login to view URL]). This is the list of changes we would like to see: [login to view URL] right column to 620px (left padding 10px, content 600px and right padding 10px) [login to view URL] Breadcrumbs over the product title and move to the top of right column. 3. Resize left column to max of 370px (left padding 10px, content 350px, right padding 10px). Leave contents as is. 4. Place a divider of 15px of space in between columns 5. Instead of having images one after the other, we would like to have a gallery (We would be ok allocating this space for a plugin to this job). -Gallery with max width of 600px (length of pic to be resized accordingly by the gallery) -We would like to have 7 slots. The first 6 slots would be pics and the last one a link to show an embedded Vimeo video preview. -We would prefer to have the first picture to be the featured image, then the 1st picture of the gallery, then 2nd, 3rd, 4th, 5th 6th and the last slot to be a video icon that would them embed a preview video (which will be hosted on video). -Style the thumbnails with a 1px dark gray border. Some notes: -We would like these changes to happen for screen sizes with a width of 1024px and higher. -A screen size over 1024px shouldn’t alter the size of the columns (if a browser is expanded to 1280px or 1600px for example, the size of the columns would remain the same). -For screen sizes under 1024px, we would like to keep the current responsive layout. -We would like to preferably create a new layout from layout style #2 if it's possible (and add it as style number 5), but we would be ok with overwriting style #2 with the new code if easier. -We would like to add the layout into the child theme so it is not affected by future updates. -We would like to keep the original CSS styling wherever and whenever it is possible for most of the elements. Attached you will find four pics: -Current Product Layout Style #2 ([login to view URL]) -Expected New Look ([login to view URL]) -New Look with Notations ([login to view URL]) -New Look: size specs ([login to view URL]) Thanks.
