Get tons of advice. Have your accountant, your attorney, your insurance agent, your spouse and your cousin take a look at this. Get GOOD advice. After explaining your dream and your plan to lots of people, sit down with a handful of those you trust the most, and pay them to give you their best feedback. Lots of people can give you technical advice, expert advice, and even friendly advice.
Wisdom is more important, and harder to find.
Create the path of least resistence. Using the dream as your goal, and knowing the obstacles that could get in your way, begin mapping your way through the wilderness to your destination. Just as someone hiking across barren territory needs to periodically stop and check their map and compass to avoid walking in circles, business owners and managers need to check their direction and their priorities. Opportunities pop up or disappear, new problems arrive or the nature of the dream changes. All of these things will happen.
