Distribute articles and press releases

We are a UK based e-commerce platform in the construction business. For marketing purposes, we have produced 7 articles (each around 500 words) about our website that need to be dsitributed. Our target market is the UK only, so, ideally, we want to get our articles submitted on .[login to view URL] pages (or pages with a predominat UK audience). The seller needs to have a good knowledge of free article submission pages, blogs, etc. Furthermore, the seller may suggest article submission for which we have to pay, on the condition that the additional benefits outweigh the costs of such postings. Work needs to be completed within 2 weeks.
