Narrative:

I was performing the duty of a pilot in command on a FAA part 135 passenger flight from ZZZ1 to ZZZ. Visual meteorological conditions prevailed; and I filed a VFR flight plan with ZZZ1 radio before departure. I was flying a 1967 cessna 206B with 4 passengers on board.the flight went uneventful; until reaching about 3 miles south west from ZZZ. I was in a slow descent from 1500 feet MSL for a straight-in approach for runway 2 (winds were calm). About a mile before reaching [that point] I announced my position and altitude on [CTAF] (1000 feet MSL); and a couple seconds later I heard a pilot calling 'for runway 2'. I immediately arrested my descent and continued on my present heading. I keyed the microphone again and told him I'm at the same spot at a 950 feet. He responded he is at 800 feet. At that point I set the climb power and started a right hand turn still searching for visual contact. He came back on the radio saying 'man you're 50 feet above me'; I was already in a climbing turn and a couple of seconds later saw him on my left side - about 150 feet below me. It was a piper cub on floats (amphibian). As I continued my climbing right turn the pilot of a cub told me I can 'go ahead and land first'; which I declined - I was already too high and fast for a stabilized approach. He landed first and I followed after completing a wide '360'.I've made at least 6 position reports as per LOA on [CTAF] on my way to ZZZ - including 'zzzzz point' just minutes. I never heard anything from the other pilot. I even asked my co-worker - who was flying to ZZZ2 - about 10 miles behind me if he heard anything from the other airplane on his radio - the answer was no.I did not see him while doing my visual traffic scan. Apparently; we were on exactly the same path (horizontally). Only 500 feet apart vertically; and with a shallow descent angle and pretty much level attitude of my airplane I couldn't see him - he was below my 'dash' - in a blind spot.
