article writer needed 20 articles (spinned content)

I need an article writer to write me 20, 300 - 500 word articles. The article will be related to different subjects that I give you. Each artilce must also be 'spinned' which means each word/sentence must be in this format {hi|hell|hiya|hey} etc etc so that I can use the 1 article and create multiple articles from the original, there must be a minimum of 4 spins on each word or sentence (whatever is appropriate). Each article must use correct english grammer including when they are spun, bad content will not be accepted. Bear in mind that this could lead to more work, your bid is per 20 articles. All articles must pass copyscape, any copies found will null and void the contract.
