Content writer (Articles and blogs and occasionally web pages)

Num. of articles: Varies
Words per article: 600 or 2x300
Topic: Various
Tone: Formal/Professional
Outline & Structure: We work with various clients looking after websites in different industries and require articles and blogs on different subjects.
Extensive research needed: yes
Extra notes: I am looking for someone to write content for various projects in various industries. I will pay per hour but in the hour I would like 1 x 600 word article or 2 x 300 blog posts. I have been getting these done in the past from different people but would now like to work consistently with one person.

There will be a constant, regular flow of work but I need someone who knows there stuff and has a passion for creating good content.

JUST TO CLARIFY: I am happy to be invoiced per project per hour (If that even makes sense) what I mean is, we can discuss through the workstream what needs doing, and then whether it be 2 x 300 posts or 1 x 600 article you can raise the invoice for £6 once we are agreed.
