Need a script made

I'm looking for someone to make a script for me that would help me keep a ladder system for a game called League of Legends. Basically, I new map mode came out for that game and they don't have ranked for it yet. I want to have an unofficial system that keeps track though. Basically I just need a bot or something that can log on to the game, and then search user names automatically and go to their profile to look at their win/loss ratio for the map and then give them a number based on their ratio. Then have it automatically update on my site.
