Custom vBulletin 4.0 Publishing Suite Development

We are looking for a PHP development team familiar with vBulletin, especially the 4.0 Publishing Suite release. The vBulletin framework is very robust and for the most part it is good for us, we only need some basic functionality added. Whatever is added must be done in a way so patches and upgrades from vBulletin to not wipe out or over write the customization. In particular we need some customization around the header section and menu section. We also need one new type of object added (a Headline) which is simply a text string and a link to another news story. For those familiar with vBulletin 4.0 the work should be fairly simple.
