Poll on number of nights or days you can commit to play team matches

Working on my draft for the team format of the VF Circuit. Quick outline on what it is looking like...

Lets say there are 4 teams total in the league (Team A, B, C, D). At the beginning of each month, I will draw up the match ups between teams:

Month 1, Team Match 1:
Team A vs Team B (A and B team will set a date and time that works for them in which they will have their matches)
Team C vs Team D (C and D team will set a date and time that works for them in which they will have their matches)

After completion of Team Match 1...
Month 1, Team Match 2:
Team A vs Team C (A and C team will set a date and time that works for them in which they will have their matches)
Team B vs Team D (B and D team will set a date and time that works for them in which they will have their matches)

...and so on. The plan is for each team match day or night should not take more than a hour (for the speedsters likely 30 minutes). Of course you are more than welcome to continue playing with each other longer.

So the question I have people that are already committed to playing in the Team Leagues or is interested. How many team match nights or days do you want per month (please take the poll)?
