Create custom product page with options

I need a custom product page designing for my opencart store, which should look similar to this: [login to view URL] I have found this module in the opencart extension store: [login to view URL] However I could do with something more custom made as I also need to add item specifics above the options like they have at midweeksong: Genetics No Sex Auto Flowering Height 80-100cm Flowering Time 8-9 weeks Seed Bank Dutch Passion Yield 75-100g, THC Level Unknown Type Sativa Dominant Also I will need to apply individual product codes & stock availability for the various options available as you can see in the opencart extension I found. If it’s possible any modifications should be made using VQMOD or OCMOD so I can update my store easily in the future. I am using the latest version of opencart - 2.0.2.0 & the Journal Theme.
