Drupal Tipster League

Hello, I have a small project for drupal based website. What I need is the following. I want to have a tipster competition on Champions League. The user will be able to log in (or register) and predict the games. He will also be able to pick the champion and get extra points. So what is the structure of Champions League. 32 teams, 8 groups of four teams each (first two teams make it to the next round) 16 teams, 8 games (the teams play two times against each other, winner makes it to the next round) 8 teams, 4 games 4 teams 2 games Final (only one game, not two) So in total we have 96+16+8+4+1= 125 games. The user should be able to predict all the games and see also how many points he has, how many points other users have and of course the results of the champions league. The system should not be 100% automatic as I will use it only once and I will be editing it (have programming knowledge). Someone who has done something similar (or even better, the same) will get the job as I need it the fastest possible. How we will work? Once we agree we set timetable, you inform me how it will be built (modules used etc), you upload it to our server, test, done. NO CSS design or design of any kind is needed. ONLY the functionality is needed (so that the league can be created, run, tipsters can predict, collect points etc) Please if you have any questions contact me!
