Blogger / Content Writer for Nutritional Supplements Website

I'm looking for someone with a passion for health and fitness and would make a good blogger / website content writer in this (health/fitness/nutritional supplements/diet) niche. The ideal candidate will be able to determine articles / blog posts to write about which fits in with the brand. Being able to do social media marketing would also be very beneficial.

As they say, content is king, so I'm trying to find someone who can make my content the KING.

Proof of previous writing / work will be required. The articles will be written in English for the UK market, so perfect grammar, spelling etc. is a necessity.
