Prestashop Module edit.

Hello! I want coder to edit existing module so that products can be sold in intervalls and it should also be possible to add alternatives to the product for example weight, color or size (S/M/L/XL). Also it needs to show the per/pcs price not the "pack price" for the product. (The total price and pack price should only be possible inside checkout.) The intervalls should be possible to be changed in product page(1), hover cart dropdown(2) and checkout page. It dont matter if this function is made using dropdown or using -/+ buttons, just use the most easy for you. Please see attached images I have made, Alternative 1 is if we make it using no-dropdown, and Alternative 2 is if we use dropdowns to change intervalls of quantity.
