Hello,
You're looking for someone to write top quality articles; so you certainly need to hire someone who has both the heart and the skill to match your needs.
What I understand is that you need someone who's intelligent enough to find/choose relevant information, synthesize them and organize them well in your article. Your ideal writer must be one that cares about you as a customer and about the high quality of his work.
You need someone who can write with style and make your article sticky, make it spark positive emotions and make your readers curious enough to keep reading.
Please let me help you, I'll provide just what you need.
I'll pay close attention to the content of your Xls files, search for the missing information, have it validated by your team and I'll make sure you are totally satisfied with the article.
Also, I can show you some of my previous articles, if you want me to; they might help you assess my style, grammar, citation, originality, etc..
Feel free to contact me for any further information.
