Resume achievements-certifications while unemployed

Hello, I appreciate any recommendations,

I am currently unemployed and wondering how to add content to my resume that I've accomplished while unemployed. I own the resume workbook but didn't see an answer (perhaps I missed it). I am presenting to a professional org soon, and additionally expect to achieve a certification. Both are directly relevant to any job applications. What should be the header? I'm also wondering how to accomplish the same thing on LinkedIn. I know many people put "freelance consultant" - and in my dreams I would be able to honestly make this claim. But I cannot truthfully say that at this time. The presentation is unpaid. I'm looking for jobs as a presenter or trainer or where at least these demonstrated skills are highly valued. I need them on my resume and profile. What header for these and possibly other accomplishments to separate my name-address info and my most recent job?

Thanks for any ideas, Jeanne
