10 model train articles (z scale + n scale)

The articles must be unique and pass copyscape and they must be at least 450 words each. The 10 articles are to be returned within 3 days and Payment will be made through GAF only. A keyword phrase will be supplied for each article. The articles must be written by someone with English as a first language. The budget is fixed and I am looking to pay around $3 per article. Bid is to be placed for 10 articles total. Do not bid if you cannot adhere to deadline as the work will be reallocated once deadline has passed unless an extension has been agreed upon.
