I want a blog post written every 10 to 14 days based on something relevant.

Num. of articles: 15
Words per article: 200 to 400
Information for the blog/website: The site is a big data, data analytics site - the company wants to attract new clients and would like blogs written on subjects around data science, big data, data driven sales, retail data, transport data etc
Industry: Technology
Topic: Data Science
Tone: Informal/Casual
Outline & Structure: This would be used for SEO etc but the main thing is to have articles that we can tweet to and link back to. Simple paragraphs, maybe a picture as well.
Extensive research needed: no
Extra notes: Not extensive research - but I would like it topical as well as relevant to changes going on in the world - the focus would be UK, Europe, USA.

I have put £20 - this would be per article. I would like a long term relationship with you over 6 months and more.
