Build me a ecommerce website

My website is [login to view URL] which I've just launched. The whole point of the site is that it allows people to purchase "packs" which contain players for "Fifa 15 Ultimate Team" People purchase packs and whne they buy it the pack opens, they will then list a player and for the amount that the players in the pack are worth. So in order to assess the amount each pack is worht and to also attain thedatabase of players required, you must get the players from websites like futwizcom ( I wouldn't really know how this would work) Also see attached document for more details) Discuss with me the product further as its hard to explain.
