Hiring, Someone who can make a mystery box plugin

Making a plugin that can create lootboxes,

people can open lootboxes when they are registered
When they open the lootboxes they see an animation and show what they win (they can open the lootbox after x amount of time)
They also immiedatly recieve the winning thing in the dashboard (Inventory)

In the backside:
I want to edit the odds of them winning, change what they can win, change the lootbox

Also Coupons should be auto generated, based on their email+random code+the amount the coupon is worth

If you are able to make this, let me know.
Should work on a wordpress site.

Budget: Seeing what people ask.
