Build a CSGO Jackpot WEBSITE

I need a programmer to make a website like where some random steam players put skins who worth somes $(the higher the value the player bets, the higher the chance he wins the jackpot - ) or more and when the pot hits at least x (definable via config or admin backend) entries or 5 minutes the system randomly selects one player and all the skins of guns in counter strike global offensive is awarded to him through steam trade offer. This would be using Steams Trading Link system and steams api login. I'll also need a bot (i'll be able to give you a bot coded in node.js that got a lot of bugs for make you understand what i need )who will accept all the offers that come from the users , and at the end of a round will send the winnings to the winner. Parameters that need to be set via config: Number of entries to calculate the winner, house edge in percent to keep after every round. exmple : [login to view URL] [login to view URL]
