Your price is fine by me.
I am ready to work with your deadlines. I am generally able to write 2,500 words per day, so 50,000 words per month won't be a problem.
Although I am not a native English speaker, I have great command of the language. I have created unique, original, and SEO-oriented articles in a variety of niches. You could check the samples of my past projects in my portfolio to see if my English and writing skills are good enough for you.
Looking forward to our cooperation.
Thanks
