Item price-carton price-contained qty of items per carton on Product page

[ilias61]

On the product page we need to show the item price, but the sale is for b2b on cartons basis, each carton containing specific number of items.
For example, selling bottles, each bottle price is 1eur and the carton contains 10 bottles, so carton price is 10eur.
So, we would like on the admin side to set the item price & the qty of items per carton in order to automatically have on the front side of product page in addition to its photos and description, the price per item, qty of items per carton and ordering qty of cartons with corresponding no. of contained items.
Any idea how we can do that? (we donot want to use the "minimum order qty" as it does not ensure an integer number of cartons ordered)
