I'm not a Pro or expert, just a pond junkie.
First, find out what the Owners goals are, write it down to develop a plan to maintain and exceed it. What kind of budget can you get?

They understand that it all starts and end with forage amount and quality. Water quality can have a huge effect here. Start a catch log and identify the RW of all fish caught. See
