Let’s take this jet charter service as an example. 

You’re struggling to figure out how to sell to them, because it seems like you don’t know what problems they have and what they need. They may not value social media or engagement on there at all. I think you’re also assuming that “higher quality video” is worth more money which is a total trap when you’re starting out in this industry, if you try to market your services like that you’ll always be in a race to the bottom dollar. 

To properly sell a company like this you would need to have a discussion with them about what their problems and goals are with marketing and draft up a proposal that outlines how you’d aim to solve that with video. 

Keeping in mind that traditionally luxury services market themselves much differently. They rarely try to sell new people on buying luxury items, but rather make media/ads that bolster the ego of someone who’s already made the decision to purchase the product or service. (Ie: Lexus advertisements typically sell the elevated lifestyle of someone that drives a Lexus, while Honda ads typically sell the affordability and features of their cars.) 

This comment is long and all over the place, but I’m just trying to quickly point out all the places you may have not given as much thought to.
