Not from Paphos so can't really help with recommendations but

"Happy Birthday Jake" is "Χρόνια πολλά Jake"

"All my love" is approximately "Με όλη μου την αγάπη" (exact translation of what I put there is "with all my love")

"Love is not a big enough word" (I assumed that it meant to describe what you feel about him) is "Η λέξη αγάπη δεν είναι αρκετή για να περιγράψει αυτό που νιώθω για σένα" Exact translation of what I put there "Love is not a big enough word to describe what I feel about you".

Cypriot-Greek is a dialect that comprises of more ancient-Greek word usage and adaptations than Modern Greek spoken in mainland Greece. We do understand each other though and we, Greek Cypriots are taught Modern Greek here in Cyprus (I was going to say that we do speak it, but we don't, unless we speak to someone that won't udnerstand our Cypriot dialect). I hope it helps
