Article Writing Services Needed

We are looking for a partner for ongoing article writing. The job is to produce a series of UNIQUE 1200 word articles in English around the keywords we will give you (3no per 1200 words) and supply us with copyscape passed articles, that copyright will be passed over to us. These articles will not be reused for any other clients. We will retain all copyrights and ownership of the articles once they have been approved and paid for. This is an on going project, and not all of our requirement can be serviced by a single company / individual. If you are able to right spinnable articles this will be an advantage (you will know what spinnable is if you can do it). We would also like to see a couple of similar articles you have done with your proposal. We invite proposals from Native English speakers, residing in the UK only. When you submit your proposal please base upon a minimum of 2 articles to be done in the first instance as a trial. Any questions please ask. Thanks
