Website collection descriptions & Product description SEO

We are a wedding and events company and recently had our website designed on shopify, We are now looking to get 12 collections description and also the products within each one of them. These are 65 in total. I would also like shopify SEO to be done on them which make it very important to know how shopify works. It is also essential that all descriptions are not plagiarised as this affects our business and reputation for copyright infringement.
