Build Lootbox for Website

I am looking for a developer to create an animated lootbox to sit on an existing website. Customer will purchase a lootbox from the store, be emailed a code with a link to the lootbox site. put in the lootbox code and an animated chest will open with their items. They can then exchange the items for real world products. CUSTOMER JOURNEY - Web application hosted on website Client visits site Selects and Purchases one of 3 chests Pays through online payment gateway OR requests bank transfer When payment complete we send them code which they enter into the lootbox game They click on the Chest tab on the website They are taken to the Chest game where they are asked to enter their code They enter their code and click enter Animation shows them their Chest (3 types of chest) They click the chest and it opens in an animation out of the chest appears their items. Items are already pre determined per chest (no need for randomisation) (3 types of items) They click each item from the chest and it gives them the list of products they can exchange that item for When all items have been exchanged for products they click confirm They then see a confirmation on the screen of their order They are sent a confirmation email with their order. We also receive the order via email. They then see the start page where they can enter another code.
