B2B Content Marketing in Germany

This project is for a Czech Software company that makes products related to electronic signatures (electronic time stamping to ensure they don't expire) and digital archiving. We are helping them launch their product in Germany. The main challenge is to convince IT managers & legal teams in mid-size companies that they need this thing to make their long-term digital archiving fully secure and future-proof. To create this need and establish the company, we need to do a lot of content marketing. Both PR-style stuff to get customers thinking about the risks of not having more secure digital archiving, and everyday online content (blogging, discussion forums) to build links for SEO. It would be a combination of mainstream writing for CEOs/legal teams and more technical articles for IT managers. I'm looking for either: a) A German copywriter & editor who can work with the Czech (mostly English-speaking) tech experts to develop feature articles & blog posts, and then get them published in the right forums/journals. b) A German IT writer who can trial the technology and become an independent advocate him/herself.
