Website proofreading, edditing, Health food, wellbeing

Hi
We are a small business, health food, and supplements. Our website needs proofreading and editing plus SEO.
We make cultured vegetable condiments, vitamins, minerals, and organic grains. We are health orientated, we want to educate with our website. Gut bacteria and related topics.
We will need a good business story. I mean to put the story creatively together. As English is my second language the content will need English creativity.
Budget negotiable.
