Hi Melissa,
It is tough to figure out what to say as far as your website content, but I shall tell you what worked for me and hope it helps.
When you're referring to your 'introduction' are you referring to how you are going to introduce yourself personally or how you are wording your introduction or home page? When I was working on my website content, the first thing I did was list all the pages I wanted on my website, e.g., Home Page, About Page, Contact Us, Services, etc. That made it easier to decide what to write on each page. I then listed all the things I wanted to say and started to figure out which page worked best for each item.
Remember, too, that what you write isn't written in stone and you will no doubt continue to tweak your pages and content as time goes by, so you're not stuck with what you start with. It is a work in progress, so don't be afraid to write down everything you want to say and whittle it down as you go.
Good luck!
