Content Writer for Social Media, Articles, SEO, etc.

**IF YOU DO NOT INCLUDE EXAMPLES OF YOUR WORK (PREFERABLY 5 TWITTER STYLE POSTS (140 CHARACTERS) AND 1 SHORT ARTICLE) YOU WILL NOT BE CONSIDERED!** I am looking for some writers that I can call on to write content for my company and my clients. I own a social media management company and we post regular, hand-picked content for their profiles. I need someone who can write out 31 - 62 posts per month per client. The posts must be in conversational English and must be relevant to the client's industry/topics/etc. I also need people who can write keyword articles for me from time to time. Again, proper English is a must for these articles. If you are able to also submit articles to sites that would be a plus. For your bids, please include 5 - 10 Twitter sized posts about social media (as if you were writing for a social media marketing site) and one short article using the keywords "social media marketing," "SMO," and "SEO."
