Blog Articles for UK Site

We are looking for someone to initially write 10 Blog Posts on Promotional Merchandise and Promotional products for a site [login to view URL] aimed at the United Kingdom market. We have had articles in the past which just aren't good enough. Each article will be between 350 - 500 words and there will be certain keywords which will need to be included. The writer must be native English, we will not accept plagiarism (Copyscape will be used to check) and the ownership of the publishing rights will pass to us on payment. We expect a very high quality piece of work and if acceptable could lead to further work. We expect you to research the articles. Please send examples of previous articles, along with a sample article on Promotional Mouse Mats (Min 100 Words)
