You say you want to build a website? It must be feature rich, flexible, extensible, powerful, and very web2.0. This is an important site, and you don't want to be locked in to someone else's framework, so you have decided the smartest approach is DIY. You have a small team of very experienced LAMP developers who have track record building successful sites. They've promised to meet your every requirement. You're new site will look and feel unique. It will not have that distasteful look of so many of these other sites built on one of the open source content management systems (CMS) like Joomla, Wordpress or Drupal. Down the road, as you extend your website, you will save lots of money as you won't have to hire developers with specialized skills in a certain CMS. Anyone with sufficient knowledge of Apache, PHP and MySQL can work on the site. A CMS might work wonderfully in many situations, but in your case, you need the power and flexibility only offered by a DIY solution.
Sounding pretty reasonable to you? If not, you may be failing to buy in to some common fallacies.
