MEAL BUILDER & CALORIE/PROTEIN/FAT/CARBOHYDRATE CALCULATOR

I have a food site already built but need a developer to work on a page (linked to woo commerce) that allows the user to select the amount of items defined by the button selected beforehand. The page should not allow the user to select more or less than the amount defined by the button selected before. The total amount of protein, fat, carbs and calories of the selected items should be displayed also, as well as dynamically change accordingly when items are selected/deselected. These items should then be able to be added to the user basket as a single item (a plate) that includes all the selected items. Further details will be provided for the person chosen for this project.
