Any image planned by you to suit your website design? If so you must give that and speak with your web designer. He may suggest some ideas. There is a need to put everything together before coming out with a storyline. You may consider your approach like a grammar school and it also makes sense to have a digital brand story, revealing who you are and how it matters.
The planning of such as website map can be basic, but there should be a page name so that you get the layout sense. You must feel convinced about the layout to proceed.
