Hello.
First of all, I would like to say that you shouldn't be discouraged to employ me by the fact that English is not my native language, or by my apparent lack of experience in this field of work.
In fact, I've been studying English for quite a while, but rather than ranting on about it, I would be very happy to prove it by writing articles for you.
Just give me a chance to do an article, and I promise you, you will be very pleased.
