I had an old Glastron Runabout that I converted to a fishing boat. I had the jump seats also. I removed them and put in exactly what you're talking about. I got the seats on line, I think 2 for $50-$60. Got em online, just can't remember where. They were just the cheap Wise seats but comfy. The pedestals and swivels from BPS. It was definitely under $100 to make the conversion. You will be surprised how much walking around room you will have after its done.
