One thing to keep in mind with this project, however, is the fact that vBulletin can only be installed on a single domain. This means specifically, if you're going to create separate websites for the forum, blogging system, daily news, classifieds, ect and plan to use vBulletin addon's and plugins to present these, you will require a separate vBulletin license for each domain.
If you do not have an overly large budget, I would figure out a way to present all the information through the single domain and simply provide links to each
