I'd like to accommodate 7 to 10 players and the tourney could last 3 to 4 hours.
I think there is one thing to take into account: Only 4 of those are regular poker players. So I think it would be better to have a slow paced event. Not TOO slow though, because the others can get bored.
This is for my birthday barbecue. The other days we're going to be playing with 4-5 people that are really into serious poker. So I can use the suggested T1000 I found here with my chip set. It can also be faster.
I think there are more variables here than I was expecting to deal with
