Company forms site

Hello! I currently handcode a website that my company puts all of our internal forms and other information on. I would love to automate this as it grows bigger and bigger and handcoding is a PITA. So since I already run 3 WP sites, I of course first thing of using it. Links and static pages would be great and easy, but the biggest thing I need is to upload forms, which need to have categories, at least 2 levels deep, possibly 3. It would also be nice if there was a way to batch upload them, since that would make initial setup easier, but it’s not essential. Also good would be a way to replace a form when it gets updated, without having to delete and reupload it, like an update button or something.

Is there anyway to do something like this? If not, is anyone familiar with a good cms that would do this?

Thanks
