My huge experience as an editor/proofreader, researcher and academician places me in a great position to prosecute this job on your behalf. I also possess an excellent command of the English Language coupled with a very broad and resourceful vocabulary. Although you didn't state what field the article covers, I am certain that my versatility, research experience, analytic ability and dedication will prove vital.
If you want the article completely overhauled and rewritten, it will definitely take more than 3 days to complete. However, if you are only interested in editing it, I can do that for your advertised price of $88 but that should be exclusive of the Freelancer fee hence my total bid of $97.
I wouldn't advice you to give this project to a team of writers because their flows of thought and individual perspectives might vary and this is capable of generating a discordant piece.
I guarantee your research paper will be error free, grammatically correct, devoid of plagiarism and with an intellectual twinge. Most importantly, it will be completed within the stipulated deadline.
I am your man.
