Blog Content Writting

Need unique content copywriting for my blog 2-3 short/quality content or articles per week being posted to my blog. this project is for a month, so if we are having 2-3 a week then that's around (8-12 articles a month) topics must be about web design & development/graphic design/logo design/seo/online marketing etc (prefer someone with good background on these topics) - i will be giving bullet points to assist for each article writing. All content must be original, unique, seo copyright and must be checked through copyscape to prevent plagiarism and to prove that its original and not been copied from somewhere. I prefer someone with strong seo background on blogs (wordpress) so he/she can use the appropriate categories & tags so it can help to drive traffic through organic search engine results.
