Build a Website(Casino csgo)

Hey Freelancers, i am looking to make a website like [login to view URL], [login to view URL], https://www.skinsvault.com. We have design ideas, so you wont have to be the designer of the website. We don't actually have any html pages with design or anything, we just have an idea of how we want the website to look. It's kind of like a casino with skins from the game Counter Strike Global Offensive.

For such a website to work we need to make a steam-trade bot, that can trade with the users on the website, both take the skins they want to bet, and give them the skins they win. Also we need to automatically get the prices from the steammarket to know the value of the skins the people place in the pot. Here is a link to some help about the steam-trade bot [login to view URL]
