Research based content for technology 500-1000 words

We need an accomplished copywriter to work with on a regular basis to provide well written, researched content for blogs, articles, opinion pieces. We will provide the scope of the the content piece and keywords, but will expect detailed researched and stats to be included in the article. The articles may also be focussed on specific geographies. As a result localised stats and content connecting to the region is necessary. The articles may be between 500-1000 words.

We would like the prices for 500 word articles, 750 word ones and 1000 word ones.
