TurnHere is a pretty cool video service. They have a network of videographers available for hire. You contact TurnHere, tell them what you want in a personalized video for your business and they make it happen. To jump start the market, they've been doing book promotions with a large publishing house. I saw this video highlighting Tonya Reiman's book on their blog. Great little tidbit and shows how much more likely you are to buy something once you've had a personal introduction through video.
