CREATE SHOPIFY APP NODE.JS

We need a custom shopify app created almost exactly like this one: [login to view URL] Except 3 KEY DIFFERENCES: 1. We need the list of products displayed on the results page to be in a table, list/table format similar to this: [login to view URL] (see the list of parts on the right side of the diagram image) 2. We need the diagram image to appear at top of the page, when user selects 2019 -> Cobra CX50JR -> Airbox that page should have a way for us to upload the Airbox diagram image. 3. We need to be able to ASSIGN A DIAGRAM NUMBER from the diagram image, to the list of products being added. So when we add a product to the list, we want an extra custom field that says ok this product is #31 in the diagram (for example) - ALSO the diagram numbers should allow to contain letters also, incase we want to have a #3A, and #3B, and #3C for example. Again, see a complete working example of what we need on our current site, based on wordpress: [login to view URL] These are the only 3 key differences we really need, other than that, this shopify app should work exactly like the one provided in the example, including the front and back-end. ***NOTE*** WE WILL PROVIDE FREE NODE.JS DEV ENVIRONMENT ACCESS TO DEVELOP THIS APP IF YOU ARE CHOSEN. PLEASE BID ONLY IF YOU HAVE SHOPIFY APP EXPERIENCE, AND PLEASE SHOW US WHAT SHOPIFY APPS YOU HAVE COMPLETED IN THE PAST. PLEASE INCLUDE YOUR BID FOR THE FULL AMOUNT TO COMPLETE THIS PROJECT.
