I just found out about a small external hard drive that looks like it can be used to send large files (like raw video files).
Here's the link DiskGO Drive (http://www.edgetechcorp.com/storage/portable-hard-drive.aspl)
I'm going to order one and send all my raw videos to JColgan along with a return label so he can send it back to me. (Maybe even with footage from other units.)
Don't worry, the finished commercial will be in there, too.
For video editing, I use Pinnacle Studio, but I've found that Windows Movie Maker also works pretty well.
