Looking for a hosting platform/web host with multiple users to blog and host other websites

Hi all,

I'm looking for a platform where I can give permission to other bloggers/editors to write and post articles.... I came across Ghost, not sure if anyone here have used it.

Also I'm looking at starting couple of landing page/funnel sites for my clients - does anyone know of a good platform ? Lead pages came up on a search but I want to be able to run few at a time at a reasonable price.
