Proofread & edit customer surveys - ongoing

Hello, I own a company that runs mystery shopping programs in Australia. I'm looking for someone to join me in an ongoing basis to oversee survey editing for my mystery shopping business. From the get go it's important that I make it very clear - I need someone who is proficient in the english language. Beyond that I need someone who can rearrange sentences & sentiment to ensure the comments are written well, and that there is consistency across all of the survey data. I can show you examples of what I expect so you can edit & adjust accordingly. I would require weekend work one weekend of the month (a set weekend, maybe 5 hours, quite time sensitive so it's important that you can be free to do these) and probably 2-3 hours each week. This will start to increase. I can teach you most things, however I need to reiterate the point that your english & writing skills are impeccable. I have 16 surveys that currently need to be edited. This is a good way to get started and understand the nature of the work.
