I'm not from the US but without a doubt, I have a good grasp over English (certified an A* by Cambridge Examinations).
I'm a blogger and I have a good knowledge of SEO. Not only will my writings be 100% original content, but they will also be free from any grammatical error. I have past experience in writing SEO optimized articles for various different niches like health, beauty, fashion, online income, advertisement, reviews, etc. So I can definitely write on any topic that you'd want me to. You'll only pay if you're satisfied with my work.
I'd love to work part-time for you on a regular basis and I will always be truthful about when I can truly submit a completed article to you. If I say I'll finish overnight, overnight it is. However, I hope we can have a private conversation about how many articles you'd need per week and all those details, before you decide to hire me or I commit to anything.
I can send you some of my past work if you're interested, just send me a message. :-)
