develop a site

Hello, Lets explain the basics, I came with the idea to make a gambling website for a game called Counter Strike: Global Offensive (shooter). This game is part of a gaming profider called Steam - Steampowered.com. In this game there are weapon skins ( the look of a weapon ) you can see here [login to view URL] basically this are items that you can use in the game. Since a few months a couple of websites around this game have already launched with the idea I have. The gambling part is that people can gamble their items(skins) and have a chance to win or lose. There are already a couple of gambling sites that have the idea worked out and those websites are going really well. The website will need to work actually exactly the same like theirs. Here you will see some of the sites, [login to view URL] and [login to view URL] The point Basically, players deposit skins, once a pre-defined threshold is reached a depositer will be choosen, with odds based on the values of it's deposited skin, and awarded with ALL the skins in the pool. "copied" What the web developer needs to know as far as i know that is needed (I am not familiar with coding) Databases to store the history of the players their bets PHP, HTML, CSS, MYSQL STEAM api [login to view URL] Regards.
