Actually I haven't any samples to show you, as when I wrote something I didn't do it in a professional way with the objective of building up a portfolio. I will start doing it from the works I will do as a freelancer here.
I have a strong technical background as I am a Systems Analyst and I usually read a lot of Manuals, as I have been being a Free-Software-Tester for the last 18 months and I love doing so. I also have a vaste experience in online courses as a student, so I can feel at the first sight if the article is clear and concrete or if it has too many words to explain such a simple concept. But despite of these, I focused myself in Spanish, German and French Translation to take advantage of my native language.
I've read the sample you sent me, and I think I could write the same way, moreover if you want short articles of no more than 500 words.
I offer you to send me a topic of which you want an article, and I'll do my best writing it freely for you. Also, I could translate it to spanish to enable you to test my skills. All free of charge. Please visit my website to find out my data.......
Perhaps I could write about certain concepts I have incorporated the most due to my interests, so let me try with no obligation. It's a good challenge for me and I might discover the writer I have inside and never noticed!! I would want to know the scope of concepts you will cover.
And please, if you give me the opportunity, give me also several days, as I am doing a translation now and I must finish before the deadline.
Thank you for the opportunity you are giving to me. I really want and need to work.
I look forward to hearing from you.
P.S.: I apologyze for not answering you earlier, but I had to write a complaint to the webmaster of GetAFreelancer because I couldn't post messages.
