This covers any type of marketing done for free by an influencer, including shoutouts on social media, product reviews, endorsements, mentions, and more. Many influencers are willing to help you distribute your content in exchange for something, maybe a reciprocal mention, a trial of your services, or an ongoing relationship. Think about what you’re willing to give for the promotion of your video. Depending on how much they can up your exposure, it just might be worth it.
The trick? Find the right influencer in your niche so that you're targeting the right audience. It's not just about spreading your message. It's about spreading your message to the right consumer base. If you can do that properly, then you can likely reach a sizable audience for not much money invested when you think about the potential profit it can return.
Professional cameras, like DSLRs, give you fine control over the manual settings of shooting video and allow you to achieve the shallow depth of field (background out of focus) that people rave about. While they're primarily used for photography, DSLRs are incredibly small, work great in low light situations, and pair with a wide range of lenses — making them perfect for video. However, DSLRs do require some training (and additional purchases) of lenses.
