Display/Hide Field Values Based on an Account Field

In my scenario I have several different user account types. Each user account type is paid for a specific order based on a commission value or fixed fee. For accounts with a fixed fee, I want to hide the fee value. Even though the orders table and the accounts table are connected, my options for displaying the fee field or not is restricted to the order table fields. Anyone have any suggestions on how to accomplish this without having to create a second view?
