How do you say How do you write Love, Trust and Hope in Greek?

How do you write Love, Hope and Trust in Greek? Love - αγάπη Trust - εμπιστοσύνη Hope - ελπίζω Is what I get from a translation. The reason I ask is because I'm going to get a tattoo on the back of my neck this coming Friday, May 8th. Also can they be written vertically, or must they be written horizontally?
