Favor needed

I have a favor to ask of anyone in the northeast. The Transcending Boundaries Conference I'm part of has just hit a major snag regarding our A/V equipment. We thought we had a source for what we needed, but they just backed out on us. So if you have any of the following that we can borrow for the weekend of Nov 20-22nd I would greatly appreciate it. I can come pic it up, and will personally keep track of it (and store it under lock & key before & after the con and when it isn't being used at the con).

What we need:

• up to three projectors (of the sort that plugs into a laptop).
  
• microphone/mic stand/small amp & associated cordage(for a 1-person play and the keynote speech so it doesn't have to got to 11)
  
• Something capable of taking audio output from a laptop and amplifying it enough to be heard by a room of people (powered gaming speakers? adapter into amp above? Whatever might work we'd be glad of)
  
  Please feel free to pass this on to anyone you think can help and/or give suggestions as to who/what to ask. Any help greatly appreciated.
