Hello,
This project proposal looks like a very interesting one. I believe that writing a 500 word article will not be an issue for me, and I can provide the work as quickly as you desire, well within the two hour limit that is stated. As a newcomer on here, I know that there are others you might prefer, but I assure you that I will provide quality work, and that you will definitely not regret it if you accept my bid.
I will complete the work, and get back to you, and even make any revisions if needed. Please contact me to further discuss any issues.
Thank you,
WriterParker
