There are a number of important questions that will influence your strategy to monetize your healthy list of 60k leads.
-Do you have a product to sell? A list is meaningless unless you have a credible offer that resonates with your leads.
-If you don't have a product, can you create one to match the interest of your niche? If not, can you partner with someone who has a relevant product but needs a big list? Or someone who wants to "rent" access to your list.
-You can also consider starting a blog/newsletter to deliver industry-targeted news and content...which can be later monetized.
I, too, am in the filmmaking space and have a lot of experience with this. Feel free to reach out if you'd like to set-up a strategy call. Would love to help!
