I am creating a website for someone, it requires a specific design they have asked for, however it requires some elements of a CMS.

I understand that you can only customise the look of Drupal/Joomla to a certain level, what i essentially want to do is create my own html page, and embed functions like a blog and story board etc....

Are there open source products to acheieve this, or do they all provide a complete solution like drupal?

I cant see how i could customise drupal ot joomla to the level i want, it seems you can only change a few skins.

Should i be looking at CMS systems, or attempt to write my own blog etc with PHP?
