Creating a random items store Dota2 and CS GO

Creating a random items store Dota2 and CS GO. The पाठ छिपा हुआ or analogues.
Also, the creation of a script for “Random” things in games (CS: GO, Dota 2) and a bot for Steam. The essence of the script is that the user buys an item in a store of different rarity (rareness) and he can fall out of this class, both for 100 rubles and for 3000, and the cost of such an attempt is 500 rubles. Work with Steam APIs, tradeoffers. It is still unclear, perhaps the script will be purchased separately, then only its integration into the site / store.
In the future, there may be additional additions of some sections/features for selling things from other games.
P.S. First of all, applicants from Ukraine will be considered.
