Help required to adjust CMS to a site.

[WMD]

Proud and overwelmed with work owners of Vivvo CMS require help from an individual who will be able to integrate CMS with a site. Nothing fancy - in fact many features of Vivvo CMS are not required, but there are 2 subcategories where access is only with username & password. Those subcategories will have a slightly different headers (2 different GIF logos) and 2 separate news content.
Anyone?
