Hi, my name is David Dunlop, I'm a British writer living and studying in Czech Republic.
I had to learn Czech language when I moved to this country, and I'm also learning German and Dutch. Therefore I believe that I fully understand the struggle of learning a new language.
As for my writing, feel free to contact me for samples of my work :)
I charge 35 euros per article.
Due to my experiences on Freelancer.com I have three criteria - 1) I do not begin any work unless a milestone is issued and 2) I do not do rush jobs - e.g. "write about this in 8 hours". I focus on quality, rather than quantity. 3) I do not wish to accept payments "per word" or "per hundred words". I wish to be paid for a medium length article. This allows me to focus on the coherence of the article and readability, rather than "stretching it out" to get paid as much as possible.
As for the deadline and the word count - I can promise a deadline of 2-5 days, including weekends. I cannot promise exactly 500 words, and you should expect anywhere between 400-750 (most likely around 600). As I mentioned, you are paying me for an article, not per 500 words.
