The BIDA dance is a relatively high effort contra dance. We have signs, lights, windows that need ladders to open, we bring our own sound system. Starting February 18th we're having twice as many dances (1st and 3rd Sundays) which means the people who normally do this work might not be able to do it every time. So: more documentation, more knowlege transfer.
$5-$10 sliding scale, "pay what you can"
Take a ladder and open the windows appropriately.
Put fans in them. Make sure the fans won't fall out. They do better on their sides. Fans live on stage.
Put the green fan and any other fans not in windows where they can blow on the dancers. There's a shiny metal fan for the musicians if they want it.
Fill water coolers and have someone help you carry them out to the ledge in the hall.
