Aside from the great advice you've received already... consider Influencer marketing. There are aspiring course creators that are in FB Groups, Instagram and also scope out "business coaches" with "fans" in a sweet spot between 2k - 25k. These influencers are big enough that they do have some reach and small enough that they are willing to potentially entertain an affiliate arrangement with you and help promote your product in exchange for free access (and the super affiliate commission structure) - especially because a recurring commission is very desirable for business coaches. Same goes for business podcasts - there are so many small podcasts that would be willing to promote your product in exchange for an affiliate commission. Good luck.

While you may have diverse experience in different sectors, industries and/or clients - your personal brand can be synthesized so that it captures your zone of genius... the thing you are know for. In my case, I worked in consumer packaged goods and consumer brands... but when I went on my own in 2013, I thought the same... how can I get into this entrepreneurial space with what I know? What I found is that strategy is my "zone of genius" and I'm proud to have diverse experience because I bring a breadth of knowledge from Fortune 50 to small business...every business needs strategy. So now back to you... focus on the "zone of genius" value you bring to the table.. the mindshare you capture in your prospect's mind. The goal is to be known for one thing... niche down as a matter of strategic advantage so that you can be known as "the one" to go to for that niche. Create your unique mechanism for delivering that "one thing" and position yourself uniquely in your space.
