Need a travel agent recomendation for Turkey & Greece

Looking for Travel Agency recommendations exact dates to start are flexible within April. Tour should start or end with a couple days touring Athens and immediate tourist sites around. I want a trip that includes a couple touring days in Istanbul -spice market, Hagia Sophia, Blue Mosque, Grand Bazaar, a Bosporus Cruise, Topkapi Palace. also want three or four day cruise in Greek islands. I’d love a cruise that went either from Greece to Turkey or opposite way because I’d like to stop Kusadasi to see ancient city of Ephesus on the way- Greek islands stops, hopefully- Santorini, Crete, Rhodes, maybe Mykonos - I know this may not be possible now but I'd like to talk w/ someone who can discuss options.
