Opencart changes - display cheapest option product price and css change options

I will import a lot of products with each product has lots of options. These options will have separate prices, and I want to show the cheapest option price so I don't have to change all prices manually. Also: the options are imported like this: 1251221*materiaal=synthetisch rubber*diameter >= 20 mm*kleur=rood*hoogte=10 1251220*materiaal=synthetisch rubber*diameter >= 20 mm* kleur=wit*hoogte=10 This has to be nicely fitted in some table with the text between * and = above as table headers like this: materiaal diameter > kleur hoogte 1251221 synthetisch rubber 20 mm rood 10 1251220 synthetisch rubber 20 mm wit 10 So people see instead of a dropdown menu a table in which they can select the product article id (the first number) or the price. And be able to select the quantity of those options. Let me know what you can do Please ONLY react if you have experience in this. Other reactions will be seen as SPAM.
