N-Control foot throttle and trim pedal is the only way to go IMO. Been running them in my boats for 15 years now. They can be purchased through CP Performance. And yes, you can run hand throttle with foot throttle - I had that setup in my first 28 Skater. You'll need to contact Mike Mays directly at CP to get what you need to make that capability work. I attached pics of the 28 that had that setup.
