Content for website needed SEO

We have just had a new website built that is almost ready to go live. We need content written for the website to help with SEO and also to make each product sound as attractive as possible to buyers! We sell organic baby clothing and maternity clothing. We also need the information pages to be written using html code. There are probably 60 products that we need good descriptions written for and 9 information pages. Some research is involved to get good content for information pages.
