As I said, I won't award you for the context. Nevertheless, I would like to propose you a dedicated contract for the production of 8 articles by January 31st, 2017 coming from your list.
The topics are:
1. Start of the Art ways that can help make you a consultant
2. top ten secret of building an IT team you can be proud of
3. indulge your employees (and yourself) after a week of hard work
4. why you should stand up for your employees
5. 5 steps to ease your staff into your digital workplace
6. 10 tips to jumpstart your startup
7. mentor mentality: what it means to be a leader today
8. the art of taking care of your clients
If must be about 500 words, with a free picture as illustration. I propose 1 payment milestone per new post. Each post will be reviewed 1 time by me to share my change requests before the final release. Before the production of any post, I'll share with you my guidelines concerning the tone of the post, and the focus I want. It's very important that each post reflects my personal opinion.
As it's a mid term engagement with a significant amount of production, I propose a contract with a cost per article a bit lower than the one you propose. 25e per post is a bit high. I propose 20e (the average price I can find with a good anglo saxon writer).
If you're ok, I'll create the milestones in a second time.
Do not hesitate to contact me if you have specific question.
