This is not a translation job, but the client needs your opinion about the quality of existing translation, please see details below:
We have received some documents from A.A, Alcoholics Anonymous, an organization that helps alcoholics to get sober and things like that.
The translation was done by an AA member, who is not a professional translator. Please use a minimum time to check some chapters of the translation and let us know how good it is so that the AA member can make edits to it. The client suggests to use chapter 4 and chapter 5 for the review and any four additional chapters of your choosing reviewed. Possibly a couple from the beginning and a couple from the end. Only mark few pages in these four chapters with edits and comments and send back the annotated/edited files attached to an e-mail.
When done, please also provide in that particular e-mail a few-sentence of a summary, an “overview,” of your findings. Like a teacher would tell a student on how to improve it....
