CSGO Coin Flip Website

Simple, I want to have a csgo coin flip website like the Duel Arena on CSGOLotto . com. To create your 1v1 game, you are going to click a button that says "Start Game". Then a square pops up. In that square is all the csgo skins that the player has in his steam inventory. Then he chooses the ones that he want to use and then clicks NEXT. After clicking next there will be an option to choose between CT or T. After that the bot will automatically send a trade offer to the player with the skins that he wanted to play with. When the trade offer gets accepted the game will be created. Then the player will have to wait for someone to join. When someone joins, they will have to choose skins to the equavilent amount of money that the game created with was. When the player accepts the trade offer he gets, he joins the game. Then there will be a countdown from 10 and after ten seconds the coin will flip. It will be a 50/50% chance that CT or T wins. The coin will make a cool animation and land on either CT or T. If it lands on CT the man on CT wins and if it lands on T the man on T wins. The one who wins gets almost all the skins from the coin flip, but the bot will take 10% of the win. If there is nothing to take for 10% the bot will take ONE item.
