You might want to invest in getting the English polished up by a native speaker. There are quite a lot of minor errors, which maybe don't matter a huge amount as you're not claiming to translate into English. But it's a good site, and contains all the information a potential customer would want to know.
Thank you for your feedback philgoddard, it's encouraging!
Indeed, I plan to redraft the about me section, and than to submit it to a native speaker..
I wish you a nice evening..
