“… making local commercials for small businesses.”
Quote from a Wall Street Journal article.
There are people that are doing just that. What would keep you from doing the same? You could focus on the businesses that you really like. It could be two or three shots per video. Shot one, exterior of building. Shot 2, sweeping shot of interior. The third would be a still of a Google map with the location of the business. Suggested scene lengths of five seconds, twenty seconds and five seconds.
