Business Advice web content

I am ramping up content creation for my website. I need a writer to produce 20 pages of web content (300 words per page). After that there will be weekly articles and blogs, content for business directories, etc. The ghost written content must be unique and pass copyscape. I will own the sole copyright of all content once final payment is made. The website niche is business advisory services (coaching and consulting) and ALL content is related to this topic. I will provide an Excel spreadsheet containing the 4 main SEO keywords and phrases. Each of these keywords is to be used to create heavily optimized SEO friendly pages. I will also include full briefing documents, competitive websites and LSI keywords to make your job easier writing the content. I will also include a list of other websites with plenty of existing content to help with research. I am looking for a writer who is particularly adept at creating web content with a heavy focus on keyword based SEO. Optimally with references. References for business focused content would be excellent. I will only accept writers based in the USA, UK, Australia or Canada. The writer should provide samples of their work for me to review. As the content is created, I would expect the writer to allow me to review it before final submission. I would also expect this work to be completed within 2 weeks. I have a large amount of work coming up over the next few months, so if I am happy with the work, there will be quite a lot more on offer.
