This should be a very simple project.
I will give you access to the admin section of my wordpress blog.
You will be collecting a list themes and just creating blog posts for my site. Essentially you will be copying and pasting
4. original url.
You wouldn't be using this site. But just to give you an example. You would be copying and pasting from sites like this http://www.fabthemes.com/
You will create 500 posts.
If this goes well, I will have lots of work for you similar to this.
