Cloud and local backup solutions: advice? Consultant?

Hey Folks:

I'm trying to help an agency partner spec out their video storage and workflow needs for the next few years.  If you know of a consultant and/or have any general ideas, please send 'em my way.  Specifically, some of the agency's video post-production happens in 4 edit bays in their offices (which needs local access and then backup) but most of the work is virtual--working with remote editors like me.  

So there's two parts to this.  There's the long terms storage and backup needs for this hybrid local/virtual workflow, and then there's the workflow component (which has a local and virtual aspect).

FWIW, I use FCP but most their editing is done on Premiere.

Also: I use Postlab for my company and the remote editors I work with.  It's great for getting to a cut but then it is a proxy workflow and also doesn't cover the long terms storage/backup part of the equation.

If you have a recommendation or any ideas, LMK and thanks!!
