hey sweets, well if you have three or four acts already that's a start. That would be two acts a month: 2 months with different stuff, then you can repeat, how about one new routine every second month? You could also vary some themes. As punters change all the time, you won't have to have a new act every single time. Maybe the venue has some specifically themed nights: I guess you could change your acts a bit to suit the event...
Has the venue asked specifically to have a new act every 2 weeks?
hope that's of some help
