For a leading soft drink brand, I've written campaign charters and other internal marketing documents describing planned sales promotion programs. I also wrote implementation guides presenting these campaigns to bottlers and retailers, and wrote consumer campaign pieces. Sorry, I can't show you that sort of thing. Please contact me for references.
I've been a Certified marketing and technical coach for SiteSell's Site Build It! product. This very popular self-help package teaches people how to build online niche businesses through keyword market research, well-planned Web content development, Search Engine Optimization, and online promotion including newsletters, RSS, e-courses, autoresponders, online sales and e-goods, affiliates, blogging, etc.
