Hi, I can write perfectly engaging articles with absolutely no grammatical errors and a high vocabulary. Plus, I can write on almost every kind of topic, as long as it is appropriate. The final work will be up to your expectations and shall be submitted within the decided deadline...$1 for a 500 word article seems like a reasonable price to me. Hope you contact me soon with further details like topics etc. I can send in a sample of my writing style too if you ask.
