Have you considered a Content Managed web site?

Our Content Management is specifically made to be easy to use.

We have listened to user feedback and have refined a system that makes it refreshingly easy to update your own site without hassle.

For example, you can type or paste text in, upload and align pictures, format text and make text links to web sites or e-mail addresses. All of this control is via a familiar bar that looks very similar to the 'Microsoft Word' toolbar.

Conclusion
Use Content Management for pages that will change often and let us manually update the pages that only rarely need updating.
