I need help designing a website?

Hi, I have been asked by my school to start to build a website for former pupils who used to attend. I have the template and the design all sorted now all I need to get done is the content, but I'm having some trouble. This is the 'first draft' of the website so it just needs to be up and running for a certain event then it will be refined. So I can't make it to elaborate. But a link to photos and the newsletter and a contact us page is all I have managed to come up with. Has any one got any ideas? from experience or just ideas in general! THANKS! x
