You may have to determine if the support level you seek is in the budget.
If there is an Authorized Apple Service Provider or authorized agent that
could be called upon, as part of a service agreement or sales agreement
on-site help may be available; within a distance, or perhaps for a fee.
In these ASC discussions, most replies are from other product users and
not representatives of Apple; most who reply here are volunteers and are
not compensated for the personal time, or expense of being online; and
most of us are not in any position to gain material privilege by doing so.
You may need to escalate your interest to a higher level, and that may be
of cost; likely you could obtain qualified answers via Apple Support by phone
or via email. The ability to contact Apple Support direct, is open to you...
At least on a "per call" basis with Apple Support, if there is no professional
in your organization that can proactively seek these answers ahead of time:
re: An IT or technical expert who understands and is involved with roll-outs
of new products or services, prior to their arrival on-site, who can also be a
go-between for in-field users as well as the product maker's tech support.
