Get this Panasonic G7 kit and a Rode VideoMicro. And grab a couple of cheap spare batteries and an extra memory card.
Easily the best video camera at the $500 price level.
Both of what these guys said is great advice and you will definitely have to consider what to do.
The G7 often fluctuates in price between $500 and $800 so try and get it on sale if you can. Find a price tracker website and use it if you don't check prices everyday.
If you go with HybridCamRev's idea, I would highly recommend getting the g7 on sale. That would allow you to get an sd card, shotgun mic, battery, and a lav mic. You could also go for a cheaper tripod since the g7 is so light. Up to you though.
