Versatile Content Creation Needed

I am looking for a talented content writer who can handle a wide range of topics. The exact subject and purpose of the content is yet to be defined, but ideally a writer with experience across any or multiple of the following areas - Technology, Health and Finance - would be ideal. The word count of the articles is flexible. However, adaptability in writing styles, from informative to promotional or educational, will be highly valued. Please submit your bids along with a range of work samples.
