Article Rewriting Project (Long Term Project)

I need people to do rewrite work for me. I have both articles written and bunches of text about some subject and need this to be rewritten in 500 word articles. It's a big project. I have around 1000 articles. My budget is 250$ for all the work. It does not need to be done in a week or two. Like I said, it's a long term collaboration. Payments are done on each 50 articles completed. More details will be provided for chosen writers. If anyone has any doubt please send pm. Cheers everyone.
