As indicated in your project, the rate per article is $4, so a bid of $40 reflects 10 articles. I have written travel articles successfully for other clients, so I am sure that I can do the same for you. Further, although my location states that I am in The Netherlands, I am in fact a native English speaker from Canada, so I can reassure you that the grammar in these articles will be impeccable. Finally, a sample of my work is attached to the PM. Please let me know if any further information is requested.
