I'm available every day. After 3:30 or so on weekdays, but other than that I'm always free. I'll have my team ready relatively soon, because I know exactly what I want to make.
Sorry but I really don't want to hassle the administrators to put up a ladder for a one-shot tournament. I'm sure you can find people willing to practice against you though.
Now, if the tournament got 256 participants (extremely high for an unofficial tournament) I might consider asking for it.
