Hosting a Home Tourney, Some Questions

Ok so I'm hosting a home 24 person NL Hold'em Tournament in my basement, 4 shorthanded 6-max tables. I'm giving everyone 2500 in starting chips like the major tourney's on stars. I would like the tournament to run about 5-6 1/2 hours, and I would like there to be a lot of play at the final table. Meaning, I don't want the blinds to get so huge that the heads up match turns into an all-in crapshoot. I would like to find that sweetspot so everyone's pressured to play, but not putting such a huge chunk of their stack in on the blinds that their already pot committed. Is there any suggestions for me on how to set up the blinds, or is there any sites that u guys recommend on how to set up a tournament like this. Also, any recommendations on how to shuffle people from tables. Like should I let then play down to 3 players at each or what. Thanks in advance.

For starters, I would make sure to get this software (free d'load).

At our home tournament with similar numbers of people and time expectations, we start with 2000 chips and the blinds go up every 1/2 hour structure is:

10/20; 15/30; 25/50; 50/100; 75/150; 100/200; 150/300; 200/400; 300/600; 500/1000; 750/1500; 1k/2k/ 1.5k/3k; 2k/4k

we'd do three tables of 8. Regardless of whether you're doing 8 or 6, when the tables become unbalanced such as you've got 6 at one and 4 at two, then pick one from the 6 to go to one of the fours. you can pick by card draw or just say the person in the spot where the opening is is the one who goes- so if the opening is in the BB, then the person at the 6 table on the BB the next hand moves.
