Article Rewriting

I have 40 professionally written articles that need to be rewritten (spun) 3 times each by changing the way the content reads by about 30%.ie the start and finish etc. A total of 120 articles required. The article heading and file name of each article will need to be changes as well. For the successful bidder I have a number of writing projects that need to be completed over the next 6 - 12 months so looking for an ongoing relationship. This is a simple and easy project for someone who knows what they are doing.
