What is 'happy to help' when translated from English to Italian?

Sono felice che tu stia qui! in the singular and Sono felice che voi stiate qui! are Italian equivalents of the English phrase "I am happy you are here!" Context makes clear which form suits. The respective pronunciations will be "SO-no fey-LEE-tchey key too STEE-a kwee" in the singular and "SO-no fey-LEE-tchey key voy STYA-tey kwee" in the plural in Italian.
