Authors Needed from Specialty Websites

I'm looking for people with author's accounts at specialty sites and general content sites like [login to view URL] and [login to view URL], that can link to my sites within your articles or write new article with links to my sites. I'm only interested in authors from sites that require some sort of application process or standards, not general free for all sites like ezinearticles.com. Please PM me with the URLs of the sites you author at, the category of articles you can write, and your price for the links.
