Looking for someone to write about cosmetics

I need someone who has experience of writing marketing copy for cosmetics to do the following:

1) Enhance the descriptions of the 33 products on the site to make them more engaging and convincing. Need to increase conversions, especially on this page:

2) To write a series of blogs focused on minerals. Each week I will publish a new blog and I want to talk about Zinc one week, Potassium the next, etc etc... these are to be educational, maybe a little humorous and tie in with a single product offer at the end.

Only native English speakers to apply.

For the right person, there are plenty of opportunities to expand this project on this website including social media and to other projects/sites.
