I decided to go the forum route (again this started years ago). I do have YouTube videos, but they are supportive, not primary marketing. My marketing is done through forums, and I love it.
Just this Tuesday I had a great day, right over 2K for the day. Again, all marketing is done through forums. Even on forums where signatures are not allowed, you can still make it work there.
I know some consider forums dead, but I still love them!
