Website Content Writing

Hi I am looking to hire a freelancer on an "unlimited" monthly basis on a fixed monthly structure. The person will be highly skilled in Preference UK ENGLISH/US ENGLISH and be familiar with research and writing content for websites that will vary from industries such as accountants, solicitors, builders etc.. They need to have good knowledge of on page seo techniques for 2016/2017 and be able to work independently with little support. Details of each project would be given and then it would be up to the content writer to research and create/write content and talk with our inhouse website designers. There will be some admin and some research tasks involved and would require the person to be available from 0900 - 1800 monday to friday with some outside hours support. Rate is negotiable depending on skill, proficiency and experience. Typically amount of websites to create content for on a monthly basis would be around 50 a month maybe less, maybe more. You must have a good internet connection and be able to communicate in ENGLISH Verbally as well. I am not interested in people offering content as a one of service, but rather looking to employ someone on a monthly basis on a FIXED SALARY. If you are the correct person then please Bid, and we can discuss and negotiate rates etc... .
