.
Aegean Sailing School have a course starting on 27th march with availability. You could also try Poros Yachting Academy, based in Athens.
March is still early in Greece though . . . and of course it will be non-tidal. Nearest tiodal courses to you are Gibralter, but if I was yhou I would see if I could pick up a cheap flight to the Canaries and do a course there - lovely weather and you will get a tidal certificate.
More schools listed HERE. Please let us know how you get on.
