Need some advices!

Hello there,

I’m currently working on a project for four different churches. What I’m looking for is a kind of a portal that has a landing page with four different links. When I click one of those links, it opens a new tab with the site info and when closed it goes back to the landing page. Is it worth buying four different templates and building from scratch a simple landing page and make the linkage myself? Or is there a theme with this kind of functions?

Have a good day!
