So, I've come to the conclusion that the internet has generated another media (despite many disagreements that the world wide web isn't a"media"). And, it provides many opportunities to disclose and distribute information, and promote individuals a company, group, services and products. And it does so - brilliantly in some cases, and clumsily in others - just as other media.imperfectly.
For instance, if you're doing a shoot in a corporation and you hear the Director of Marketing discussing they need a different video for a related service or product, you should call the person that hired you (if they aren't already on the shoot) when you get a break to notify them that you overhead this information.
Your job as a freelancer is not just to do work for the other production his explanation company. It's to help them get more business! You need to keep your eyes and ears open for any opportunities your client (the video production firm ) can pursue to get more business based on what happens while you're out on the shoot.
Most people in any business (especially video production) believe that good decisions are based on facts. But, good decisions are based on opinions. You can use your skills and abilities to add the concept into the script if you begin with a hunch that is based around experience and intuition.
If you're shooting wedding which was booked by another videographer, don't even think about promoting your company. This is also a situation where you must have a small number of cards to provide prospects that are interested in knowing more about wedding video services.
So, to stick to the relationship analogy, the prospect might decide to have coffee with you (see your site and opt-in for your VIP coupon list), then visit later for a sandwich (stop by your store for more information or consult with you), then ask their friends what they think of you. You have the idea.
The great thing about the creation of movies you can get in the business very cheaply and as soon as you have created you have an advantage that offers income for perpetuity.
