Dont know about pandits, but among Parsis, Priests with a beautiful rhythmic singsong style of chanting are hugely sought after for private prayers. Either foe the departed during rhe last 10 days of Muktad (before Navroz) or for private Jashans at home and definitely for Lagans and Navjotes. The others make up the mandatory chorus numbers.
None of our priests (except the really old ones in charge of the fure temples) are full rime. They are all working professionals with full rime day jobs, who you invite ro orat for you. And who usually are attached as a body of priests to a particular fire temple. On call when needed.
During high throughput periods if the year, big cities like Bombay and Poona import priests from rhe hinterland.
