Article writing 10

I need 10 articles. 3 of 300 words, 3 of 400 words and 4 of 500 words each. I am ready to pay 0.25$ for 100 words. Milestones shall be given to the writers and will be released only when work gets accepted by my boss. Don't bid if you are impatient. I have many projects to be done so writer with feedback are highly welcomed.
