10 articles 500 words in 5 days – Repeat order Weekly

I’m looking for a native English writer for a long term project. I need someone who can write around 10 500 worded articles for our websites every week. The task will be as following –

1) I’ll provide 10 titles each Monday. You need to deliver the articles by Friday.
2) Search the titles on Google and study first 10-20 results and then write articles that are better than existing ones
3) All work must be original, copyscape passed and grammatically perfect.

Please send your best sample content in your proposal.
