Original content for 3D TV blog

I am running a website about 3D TVs and require regular posts / moderation from someone. The bidders have to be native English speakers as I require completely error-free posts and with proper grammar and information. **All articles must be ORIGINAL and not copied off any other site. I do not wish to get into copyright issues.** This project entails writing articles about 3D TVs, new developments in the 3D TV market, and making other members feel welcome. Please quote how many articles you can post per week and how much you would be willing to charge. I would prefer to pay weekly for this project and for as long as you and I are both satisfied with the conditions and work. I am also open to pay using the "pay for time" mode if the bidder chooses this but I will be stringent on how much output is generated during the time reported. The post length does not matter as much but quality and grammar do. Pictures are fine as well. Anything that makes the website interesting to visitors and informative. The website currently uses wordpress (blog). I have a lot more websites to do this with if I'm satisfied with the work.
