I'm a Christian writer who's worked for a number of years on a variety of freelance editing, proofreading and copywriting projects.
I wrote SEO copywriting articles for Net Success Marketing. I would write how-to articles for whatever their clients' particular need was, whether it was an explanation of hospice care, or tips for fixing one's garage door. Net Success would then sell the articles to companies to drive business to their web sites.
Part of this job included writing five additional titles for each article, so that the customer had their pick of whichever title they thought was the most eye-catching.
This experience is why I think I can write vibrant titles and sales descriptions for your conference.
As for a Christian background, I've attended church all my life, I graduated from Trinity Christian College, and I wrote a monthly column on pop culture for the Southern Gospel News webzine.
Samples of my work are available on this website. Feel free to let me know if you would like to see more.
I look forward to hearing from you!
