I would like to brush up my English and it's fun to see the progress!!

Over the years, I have realised English is not that difficult, (longer that hard.) with the result that today I can (now i am able to) express myself in English, albeit (though,) using (in) just simple sentences. However, I (, but i) have noticed my writing skills have suffered recently, in as much as (has set back so much.) I used to be able to write well. Once, I was adept (,) at penning (least) an essay that demonstrated a clarity of thought (can speak my mind clearly) and which was properly structured. (in proper structure.) But, alas (look at me) now, the sentence structure has become somewhat (so) weird and my writing skills seem to have deserted me. (in speaking form.)

So, from today onwards (on), I would like to receive some (get) corrections on my writing from (by) native speakers and to be able to write at least 2 essays a week, be it related to formal writing or non-formal. In return, I can help you on your Chinese writing.

By the way, I am looking for somebody to practise English speaking with me through skype. :)
Deeply appreciate (d for) your help! :)

I have suggested a few alternative phrases that you might use. Please note, I is always capitalised in English, and any reference to a language also needs to have an initial capital
