To start restructuring the way our company spends money, who should I talk to?
Experts? Contact the nearest small business development center, the chamber of commerce, the faculty of the nearest business school, and any contacts you have who seem to know planning or doing planning right.
Who to talk to? Start by talking to your father. Is it your call or his? Or should you be working together? The difference between your cost cutting and his obliviousness is a serious problem and not one that is likely to be solved by parading experts in to convince him of your conclusion, especially if he hasn't bought into the process that led to that conclusion. This doesn't bode well for your succession strategy.
