I used to work for AQA 63336 when I was at university. Was with them for about 2 years and it was the best job ever - work as much or as little as I wanted, when I wanted, and earned an average of £12 an hour. All you have to do is answer questions that have been text in through a mixture of Google/other research, past answers database and own words (for non-factual answers), although some questions did take some time.
However because it's an awesome job I think positions are rare and more competitive these days (I worked for them 6 years ago), but worth a try given your skills (research and top notch spelling and grammar).
