Drupal 8.x

Hi, I'm trying to find the right platform to build a online service on and I seriously consider Drupal due to the many modules and addons.

But i'd like some (maybe partial) input on the choice.

The platform i'm building is in some aspects similar to sites like basecamphq or podio: users will create and collaborate on the content. And they will have access to different functions and features based on the payment plan they choose.

I see this module is available. Does anyone know how to install it and how much would be charge?

I have a small group of sites from the same industry and which share much content. All of these sites share a single database and single tables. Table examples follow:

USER:
id -
fname -
lname -
email -
password
etc.

SITE: one record for each site I manage
id -
site_name - stores the site name
theme - used to select a theme
header - stores header text
footer - stores footer text
etc.

My current employer is in the process of evaluating a replacement CMS for Serena Collage and I was wondering if anyone has any experience porting over content into Drupal. Beyond that, I'd like to know how intuitive and easy to use the platform is from a user perspective. We have a variety of skill levels at the office, from administrative assistants to designers who all need to know how to use it. Specific questions I would have would be summarized in two different categories: Authoring and Programming. They are as follows:

AUTHORING
1. What is this CMS really good at? Did it match your company's needs?
2. Do you find this CMS to be intuitive?
3. Did you find it had a ton of built-in functionality? Was it all necessary?
4. Is it easy for non-geeks to use? How was the WYSIWYG editor & authoring environment?

PROGRAMMING
1. Is the back end structure the platform is built on standards, is it logical, and well-organized?
2. Do the pages it creates have simple code and does it load fast?
3. Does it allow you complete creative control with its templating system?
4. How was the support and documentation?
