120 Articles - Immediate bid selection

I need a total of 120 articles (300-350 words each) over a period of 3 weeks, that is, 40 to be delivered every week. I will pay $2 per article. No upfront payment, no escrows. I will only pay when I receive 40 articles. The first batch of 40 articles is urgent and needs to be delivered within 2 days of project acceptance. We are looking for only professional, so providers like "consultingpalace" please do not bid. Those who are interested, please set your bids to not more than $240 for all 120 articles. I'll make my selection within 36 hours.
