Hi:
Looks like you've done some legwork already, which is great because a portion of your answer lies in the work you've already done.
Who has been receptive to your past efforts?
What roles do they have?
What insights did they offer in terms of what they're looking for in projects and a video production company?
What messages of yours seemed to resonate more than others?
Now extend that into building a focused list. For example, maybe it's CMOs in a specific vertical that love your 3-minute storytelling. Or perhaps its early stage companies that are looking for crowdfunding videos.
Armed with that ideal customer, either do the research yourself--digging through websites and resources--or buy a list with some specific parameters.
If you wish to discuss, send me a PM through Clarity for 15 free minutes.
Cheers,
Kerby
