First thing you need to know about me is that I am a writer of plays/sketches/short films so I am skilled at writing dialogue as though it comes from different people which sounds just what you need.
I can answer as though it is written by an intelligent and articulate person with a great knowledge on the subject matter in question OR I can make it luc like it cums from sum1 who is not that good@ writing and makes spelling mistakes and gramare mistakes, you see what I mean?
Perhaps the answer come from person with not good English but do have understandings of question OR maybe some native speaking person with a decent grasp of the language but wrong in his judgment of the subject. I can do them all.
I can write on subjects such as, sport, politics, comedy, film, music, social problems, TV, just about anything and I am very prolific. I can write as much that can make it worthwhile financially for me.
