Here’s my advice for a magician who wanted to make a general marketing video to progress a sales process…
Maybe having a video about how to hire a magician with a lot of transparency (here’s how different magicians price themselves (I price myself based on the amazing value I provide. Some other magicians price themselves this way too. Other people prioritize taking every gig that comes in so they can offer lower rates and are less specialized.), here’s how different magicians perform(my pristine presentation is important to me, other magicians are highly skilled at jumping in to disorganized events and trying to make it work)) would be helpful to your prospects and help them make a decision. They might be looking for a super funny and sloppily dressed magician. In which case you’re not worth the money. Or they might need someone that really breaks peoples brains and elevates an elegant experience.
Educating them (even before the sales call) could be really helpful and it means you’re a trusted source. Then, they and their friends will always come to you first.
