Drupal, Zend or developing from scratch?
I will start development of a new website, it will be a large one with many features, and it will be acontinous project with many releases.

We decided to make it using PHP, but the team will learn PHP as all of us worked with Java and .Net before not PHP.

The question are: should we develop the website from scratch by ourselves, and what about using a CMS like drupal will help us or it will have many restrictions? also what about using PHP framweworks like Zend ?

I will appreciate if you share your experiences with me.

Thanks
