Tournament format?

[bhp374]

I am hosting a multi-table tourney in the coming weeks and would welcome some thoughts on pace of play/blinds, etc. I should have 30 people or so and want to do a rebuy format. I'd like the tournament to last 2.5 hours or so. Any suggestions on length of rebuy period, starting blinds, increase intervals, antes, etc. to wrap the game up in this timeframe?
