OpenCart OCMOD - Product Pack

I need an OpenCart ODMOD to build Product Packs that will function just like this one: [login to view URL] [login to view URL] [login to view URL] (demo/demo) This add-on is no longer sold by the creator which is why I am requesting it be built. SOME BASIC ADD ON DETAILS (Please review links above for full scope) The add on allows me to build a bundle product that shows up as a product in the frontend and when added to the shopping cart shows up as a product itself showing the given discount for purchasing the bundle. When a customer removes of the items in the bundle from their cart the complete bundle is removed. Please review the example demo links above to fully understand the add-on. In admin I can create a product with a price of 0, under the links tab I can add as many products as I want to the product pack items field and include the quantity of the product. Under data I can choose pack discount type of fixed or percentage and there is also a pack discount value field to enter the amount that will be discounted. In the frontend the product then shows up as a regular product with the price reflecting the discounted bundle price. The linked products in the bundle show up under a product tab “Included products”. The product of course would also show up in the search results. Note: This of course also would work in admin when creating an order (as it does in the demo)
