You can go with either a standard CMS solution like Mech Bunny or PornCMS OR you can have something custom coded just for your needs without the bells and whistles. I am having this done now with Woj, an excellent programmer and dev you can find here on GFY (or PM me for contact info).
As making things look modern a simple responsive design for your Tour and Members Area should work fine. I would check out Bootstrap, a fairly simple responsive-type software for design.
Are you still filming new content or is it all older stuff? Good luck!!
