I agree with Eileens ideas. I have afew more suggestions.

1. Write out why in this world would I as a business owner want to use dvd's over vhs. Speaking as a devils advocate, more people have vcr than a dvd player right? why would I part ways with my green rectangles to get your silver circles? Don't focus on "its better quality". Focus on benefits... what does better quality mean? Does that mean people will be more attentive when they watch? Does it mean that I will improve the image I project to show I am a progressive company? Etc, etc, etc. Take your corporate client out to lunch and ask for their input on this. Pay attention to the words they use. Use these words.

2. Narrow your target market. Who is most likely to buy video conversion & dvd authoring services? Not who can ... but who is most likely to. Like Eileen has said: "Brainstorm a list of types of businesses that use training videos." Talk to a list broker on what would be the best lists. Laser focus your target market to under 1000 businesses. 500 prime suspects is better than 50000 possible suspects because it allows you to cut your marketing cost. Sending a direct mail postcard to 500 folks 12 times a year is more affordable than to 50000 folks once a year. And its more effective. 100x more effective.

3. Put together a marketing plan on how to reach your laser focused target market. Choose 7 methods you will use to get in front of your target market (i.e. networking at chamber, direct mail postcards, talk radio, exhibiting at a trade show, etc). These 7 should only be focused on your prime target market and no one else. And I mean no one else! This is your prime target market for a reason. If it's not prime, redefine it.

4. Simplify your marketing message. Execute your marketing with consistency. And most important of all, you continously need marketing activity happening. Out of sight is out of mind.

5. Pick up and read Guerrilla Marketing by Jay Conrad Levinson. Great primer for marketing.
