I would structure it financially and start by charging enough money to make a high level of service profitable.

Technically, I would start with on-premises with bespoke hardware from Dell with a fast response service contract.

For software I'd look for a white label solution.

In short I would spare no-expense because the customer is paying for it and the more I charge the more net revenue there is at any given markup. Charging a lot filters for customers who will pay a lot. CRM's are sold to the people who write checks not the people who have to use them.

YMMV. Good luck.
