Experienced writer and PR manager (2 in 1) wanted.

Hi, I am looking for an experienced technical writer to write and promote posts on different tech websites. On a long-term basis.
He will be responsible for:

• content strategy
• creating a content (an article piece, I can provide images/infographics or statistical data if possible)
• reach to a list of different websites, talk to editors and website owners to have this content published and promoted (via their social media channels)

What is the pay, how many articles,what type of articles (or just general technology), what type of websites (do you want HuffPo quality or is my neighbours tech blog okay?). You need more information on your post mate.

Sure, adding some more details: posts should be "HuffPo quality" - sufficient to submit to Mashable, Techcrunch and this type of websites. Payment depends on the type of an article (common topic with just one link or an analytic\promo article about my company. What I am trying to achieve is to get to this types of websites with a promo article about my company + a backlink (******** preferably or nofollow).
My company is a provider of SaaS-based software targeted to collect and manage data for enterprise-sized companies. Please give your prices for what you can offer and I will get in touch with you. Thank you.
