CS:GO Item Raffle Website (Steam Trading Bot Website)

I need a website where e-sports enthusiast can trade virtual items in a pot and for every $0.01 that the item is worth, they will receive 1 ticket in a chance of winning the jackpot. The trading is completely virtual so no real cash is involved. No shopping carts or PayPal integration. Bonuses will be given for fast and timely deliveries. Rehiring for web enhancements will also be done for highly satisfactory work output. TRADING: The user will need to be able to send a trade offer with a maximum of 10 items into the raffle. There is also a concept of item expiry since there is a finite number of items we (our steam bot accounts) can hold. This would require an automated trade offer to the winner of each raffle. If the trade gets cancelled the items should be sent to a seperate bot for storage. ENTERING THE RAFFLE: Each item value will need to have a price checked in a list that I will provide. The raffle require a weighted random algorithm to select a winner. Once the trade bot is sent STEAM: The website will be using the Steam login API to register the users. This will also allow us to view the user's items and make trades with them. STEAM BOT: There is an existing technology in steam bot trading. Since there will be a lot of trading involved, the website needs to automate this process. The steam bot will be in charge of trades and verifying trades. Majority of the code is already available (in C#) but will need configuration and integration to fit the website's needs. TECHNOLOGIES: I am flexible with which technologies will be used as long as it gets the job done. There should be an admin portal in which my team can log in. I need different types of access levels like admin (full access) and 3-4 other roles with different levels of access. I should be able to create as many users as I want for the predefined roles. THE WEBSITE: The website design will be taken care of by me, all the code will be provided to the selected developer to add the required functions and integration of the steam bot. The main page will require a live feed of users who placed items in the current raffle, along with a total of the current pot of items. More in depth details will be provided to the winner.
