Unless you are good in front of the camera, I would do pictures and text with voice over. I think 30-60 seconds is a little short to get any message across, I would push to 2-3 minutes or so. They can work, but can be difficult to get some traction. You could also create a facebook fanpage and put your video(s) and stuff on there. You could put it up on Youtube, and then in description box make link to your FB fanpage and try to get people to LIKE the fanpage and try to get it going that way. Just an idea...good luck
