Tips and Advice on Packaging LinkedIn Ghostwriting Services for Growth

And I'm back to my LinkedIn ghostwriting learning session (because we're all about learning and improving today lol) Does anybody have tips, advice, or better yet, samples on how they package their LI ghostwriting service? I'm really seeing the potential of this and I'm enjoying it so I definitely want to expand it. Problem is, I'm not sure how to package it... How do you even word it? What do you include? Would love to learn more... Thanks!!
