Greetings,
I'll settle for the $2.7 net pay per article (10% discount for being a fresh freelancer). However, you have not mentioned the turn around time; when do you need these articles? I can provide high quality and context specific articles at the rate of 2 per day.
As for skills and expertise, please have a look at my profile. You can have a paid (if accepted) sample if you want it written. I've written on numerous topics ranging from bios, how-tos, reviews, blog posts, informative articles and call to actions.
Regards
