Offering long term collaboration for employers

I am a professional writer who is looking to build long relationships with different companies. I can provide articles with different themes for blogs (spiritual, technical, marketing, history, health, etc). I would prefer to receive a small amount of work per week (1-3 articles), but for a long term. My work is always accurate and original. Make your offer in the bid if you are interested. Write details about the number of articles needed, their length and the main themes, the amount given for every article. So this is a request not an offer. Do not bid if you are not employing.
