I am able to write at least two articles/day. I am bachelors from Ssuet Karachi and have excellent writing skills. I will charge $3 for 500-600 word unique article. Hire me with your rates if you are from Pakistan.
Sorry to rain on your parade, but it seems like you need to brush up your english skills. There is a great program called Rosetta Stone, which can help you do just that. It's really pricey, but gets the job done. I'm currently studying Italian with it.
