All-Ages Mobile Strategy Game Development

I'm seeking an experienced game developer to design a simple rock, paper, scissor game that can be played by multiple users at specific times throughout the day. The game targets a broad age range, from kids to adults. The game will come online and users can create input their name and battle each other. The game should be like the soccer world cup. Each player gets to battle another random online user once. The loser gets knocked out and the game continues until one person is the final winner. Once the winner wins the game, a screen shows up that says the winning player's name, date, and time. The game ends and does not start until the next specified time. Your expertise will be invaluable as we navigate this project together.
