Write me 20 unique blog posts ASAP - all on the same theme.

I need 20 well written articles of 300+ words each. They are going to be used for guest posts linking back to my site and need to completely unique (will be checked before posting) and not spun. I need to have them finished within three days of awarding the job.

They are all to be related to an area of health, which I'll give you. I will also give you the keywords I need you to include.

You need to be a good writer and a native English speaker.
