There is some great information posted
HERE that relates to ky70's method of a roundabout way of figuring out when the tournament should end in relation to the blinds. This is the method I am going to try this weekend since I get to host the tournament for the first time.
It's run however the host decides to run it. Normally, get ready for this, we start out with a 1000 in chips. No biggie right? Well, it's 30 $5's, 30 $10's, and 22 in $25. That's right, 82 chips! And the blind structure starts at 5/10 with blinds going up once an hour. 6 players last time took almost 6 hours!

So, I am going to run mine much quicker if I can.
20 25's
20 100's
----------
$2500 in chips with starting blinds at 25/50. I am going to raise the blinds every 20 or 30 minutes (haven't completely decided yet). This is going to be a tough way for most of them to play as they are used to playing almost a limit style bet/call, bet/call due to the large amount of starting chips. We'll see.
I hope this works.
