Hi at the moment i'm looking for someone who can edit my current website. I'm making a Counter-Strike Global Offensive betting site, look at to see an example of what I need to get made. I already have a bot coded for steam which at the moment accept CSGO Key's (a item) and then insert each user into a db which the website then will pick a random winner from. I need this bot and website edited so that you can bet all kinds of items and it will calculate the median of each item's value and then add the amount into %. Lets say the pool close at 100 items, 1 guy bet 10$, another one bet 40$ and last guy bet 90$. Then the guy with the 90$ will have the highest % chance of winning.
