Hello!
The task at hand seems to be right up my alley!
I've been teaching the language for the last 8 years with the organization that I'm currently employed with (have more experience that predates that) and do this on a daily basis.
Additionally, I have developed teaching content, study materials, and have trained people on varied language proficiency tests hence making it a breeze.
Let's see if we get to collaborate!
Cheers!
P.S.: I've stated two days but the time depends on how much content have you got. If it isn't too much, then it can be done faster.
P.P.S.: Kindly do read through people's proposals as interestingly for me being a language instructor (and content writer), majority of them, even the "natives," have made grammatical errors and haven't worded their pitch accurately so that should be an indication.
