Virtual Assistant for Wordpress and SEO work

I run a number of websites and Private Blog Networks which require regular fresh content of a very high standard of UK English.

I am seeking a Virtual Assistant who will be able to:
- Update Wordpress sites at regular intervals (either with hand written or purchased content from TextBroker, iWriter, five squids or a similar service)
- Use YOAST SEO or All in One SEO plugin
- Follow SEO best practices and pay special attention to maintaining a sensible keyword density
- Track and monitor rankings of various search terms in Google UK
- Set up new Wordpress websites, install plugins and populate with high quality content, images and related videos where applicable
- Research related keywords (LSI, long tail) and create / order new content to help rank websites for more search terms

An expert level of SEO knowledge / marketing (including affiliate marketing) will be beneficial. This job will be a long term position and I look forward to working alongside any serious applicants who think they can help me rank for search terms in a low-medium competition niche. I will be available most of the time should you have any questions about the project while we work together.

If you are interested, please send me your application along with an answer to this question:
