Blog Post Writing - Copywriting

We are an distributor of industrial products, and was hoping to have someone help us with some copywriting. I have written many articles as media releases for our website\blog, but they can also be posted on several other sites but I don't want to duplicate the content too much so that we do the right thing by Google. We'll get started on a few stories first, see how you can modify them for us, and if it works out well there will be a lot of ongoing work that will need to be done. As products involve items like compressors and air tools, please be aware that sometimes you need to be able to re-write technically orientated pieces - which are far from exciting, so please be aware that you're writing for this kind of audience. With the nature of the work it will involve a lot of collaboration, communication and much more. For the right writer this could be a consistent source of copywriting work as there are a lot of old articles that I would like to see rewritten for us that have been posted on some second-party websites. Please send some samples of your work, and how quickly you can turnaround articles ... :) Not sure how long it takes to rewrite a piece - the faster and better you work, the more valuable and more work you'll get! :)
