WordPress kicks ass!
I use WP for everything, from a corporate website, to a school or a blog site. It's by no means restrictive. WordPress.com might be a little bloggish, but if you're using WordPress.org independent version then you should not have an issue. If you want to do it the easy way, I'd download a ready-made theme and gradually work on the content and pages, it should be easy enough.
Don't underestimate Wordpress! It's gone a long long way since the early days. It's now the most used content management system in the world.
Hope this helps.
