Good question.
I have always had more success looking at what I wanted to do or who I would like to work for (say you are into Snowboarding, try to get a entry level job at Burton or Sims for example), then blindly poking at want ads.
Good employees are hard to find, and in most companies you will move up to where you want to be if you do well. Trying to break in at the top is much more difficult without specific experience pertaining to the position. Starting at a lower position will allow you to learn all aspects of the field / industry you choose and supply you with the information that business schooling generalizes as "widgets".
Sounds like you have an awesome foundation, you just need to find an industry to apply your talents and specialize in. If your heart is in it, you will progress much faster, stress a lot less and have a lot more satisfaction at the end of a hard day.
