Article Spinning

I need an article spinner on an ongoing basis. Sentences would need to be rewritten once or twice depending on the need. There would be some spinning of individual words too but that does not have to be so extensive. I am very concerned with quality so I need a good writer than can write at the level of a native English speaker. Please do not respond if you do not meet that requirement. These would not be big jobs, but they will be ongoing. So, I will need a quote for piece work. For example, the price for each 100 words with each sentence spun once, twice etc. I also may be interested in having you write content too. You can quote for that if you like.
