Blog Posts For Printing Website

I am looking for original content which can be posted on the blog for our printing website. Requirements include: 3 - 500 word articles on various subjects such as: EDDM (Every Day Direct Mail), Postcard Marketing, Brochure Printing, etc. We will be looking to write an additional 20 articles and will do more on an ongoing basis. Articles should be informative and include text links to our site. Writer should be be a native speaker of the english language as we will not work with companies which provide content that is not easy to understand. We are not looking for spun or writes. Each article should also have a full color graphic submitted to us to use with the blog post. Articles will provide links to the product and info pages on our website.
