These things take time. I'd love to get this idea up and running but the real world has other ideas. So this is my current plan:
November: set up this site and related accounts (Facebook etc)
December: make links to potential venues and artists. Generate a bit of buzz
January: launch a crowdfunding campaign
February/March: get everything ready and start some low key trials/practice run events
April: final practices and organise first proper events
May: launch!
