Hi,
I just activated this account here at Freelancer though I've been doing freelancing at oDesk and Elance since January,2012. My bid for per 500-word article is $3 and I think it won't be too high for you too! Take my word on this - I won't let you down. Please go through my oDesk and Elance profile links which you can find on my profile here - and you will see, I hope, that I could be the right one for this project. We can negotiate the workload and the deadlines for this project if you're willing to proceed further.
Regards,
Jamila
