All cash has been reset to 1000. Don't ask me about this again, we've discussed this in staff and it's the only (fair) way to go. If you've placed a bet at an event you need to replace it.
As for getting more cash, you can do this:
* Play and win on vBookie
* Post threads and posts (10 for new thread, 2 per reply to thread)
* You also get bonus points for referring new members and for positive rep (you lose for neg rep)
