Sales Videos:

Imagine having the perfect sales pitch, every single time you present it. Completely rehearsed with the combined knowledge and experience from the best of your sales staff. Stress the points that work, eliminate the ones that don't. Repeat with the same excitement and intensity without ever getting discouraged. That's a sales video.

Baughan Productions has been involved with many sales videos. The first one took a million dollar a year sales product and helped boost it to a billion dollar product. (Rubberized roll-roofing systems that replaced tar and gravel flat roofs)

A sales video should be only 5 - 8 minutes long and ideally it has to feel shorter.
Consider outlining your presentation in a problem/ solution/ additional benefit format.
Also consider that unsolicited testimonials are considered 3 times more effective than what an announcer says.

State your goal. Is the video just a warm up to get the viewer to contact a sales person, The total sale? A combination sales/ image video?

Baughan Productions made its own sales video for a new invention called "Levelcam":
