Thank you for you in depth response. I have found several of those links and plugins to be very helpful. My business partner and I are almost done with our multisite. I have to say that I like drupal for many reasons over wordpress and wordpress overall drupal for other reasons. Overall Wordpress has worked out better; especially when it comes to creating a business oriented multisite.
Our last hurdle was creating a global template that we could use for a customer account that could be exported and used for new customers via plugin, thereby minimizing the amount of work involved in creating a customer acount. We tried about 5-6 plugins for cloning/copying and import/export but none of them worked right, unless we overlooked one (tried wordpress import, ns-cloner, add-cloned-site-for-wmpu (batch), duplicator, wp-clone-by-wp-academy etc). They just caused problems really.
So what we have resorted to doing is creating a new site/user, using a the global theme, creating new pages, new menus then copying and pasting from the global page into the new page. It takes about 10-20 minutes, but i'd imagine developing a plugin to do something similar without any coding/compatibility issues would be pretty difficult. Unless you've heard of a different way that doesn't cost $100+? lol
The advanced custom fields plugin was definitely very useful too, per your suggestion, thank you. Again thank you for your in depth response. If it weren't for people well-versed in wordpress like you, people not so well-versed would be screwed! Lol thanks again CFS!
