Need a Copywriter VA for quality articles and some light social media posting

I'm in need of a VA for copywriting tasks and some social media content creation. Most of your work will consist out of writing tasks for website articles. These will not be basic 600 word articles, but well written 1200 word+ articles, with some pillar posts that can be triple that size. You need to have a good understanding of new tech, and be able to independently test services or products and write extensive reviews and comparison articles on these. There are also other article categories, but most will require a good understanding of tech. I'm looking for a good writer who is very inexpensive. I don't expect you to be a rockstar and I assume some editing will be required, but the better your samples are, the more likely we are to be a match. In addition, you will tasked with setting up some social media channels and creating some content for these. This is not time consuming or complex, but generic posts and simple engagement to get some traction on the channels. This task is ancillary to the writing tasks. Please include mention of the time you require to write a 1000 word article that is well crafted so I can get a good idea of cost and efficiency. Please also include any relevant sample work you have done.
