I have great command over English. I've been writing since I was 16 and I can dish out very high quality articles with perfect grammar almost effortlessly. While not my first language, my English is at par, and in some cases, even better than native English speakers
I'd like to take up article writing work that can bring me around $50 a day or so.
I've been writing optimized content specifically for the purpose of Internet Marketing & SEO for the last 4 years.
I've dabbled in nearly every big niche out there, but I enjoy writing most about Health/Fitness and Men's Dating - I find that it gives me more flow and coherence, and I can get articles done pretty quickly on those niches. That being said, on a long enough timeline where I factor in research for topics that are new for me, I can pretty much write articles on any niche, provided they don't get extremely technical or jargony.
Let me know if you're interested. $5 for 350 words sounds fair.
