Messaging for my niche

I completed a niche worksheet. And this is what I came up with ‘I help entrepreneurs who have an idea for a course turn it into a reality.’ Somehow this still seems vague. I’ve gone two levels because I’m not just helping any course creator but this doesn’t totally capture what I’m trying to convey. When someone signs up for my signature service, it’s because they have lots of creative ideas or content but don’t know how to get it structured and organized into a course. They’re creative but struggle to turn it into a tangible product. And they’ve had this idea for a while but struggle to make it a reality. It’s like they can’t get it done on their own.

How do I convey this message in my marketing?
