Automated Aquaponics System

I have a small aquaponics system that I am looking to add automation to. Looking for a freelancer with aquaponics or aquarium experience controlling valves, pumps, switch ect. with raspberry pi, Arduino or equal micro controllers to write code and advise on overall system, set up and installation. Also interested in diagraming the system and simulation of water flow etc. Please take the time to tell me about your aquaponics experience since those will get preference first. Thank you.
