I've done a few videos for my websites, a few tips
1)buy a tripod,
2)don't try and shoot it all in one take unless your video is designed to make only 1 very simple point, you will need to edit your film even if its to cut of the beginning where you turn on the camera and jump in front of it.
3) don't try and film yourself, making a video is a 2 man job even if it only to zoom in or move the camera as you work.
4)use MS live movie maker which is a free download or already on your computer, it is very..very easy to use
Use MS-LMM to put a title and end contact number on it.
MS-LMM has a 1 click Icon to upload direct to youtube.
