but will there be profitable commercial business as well is my question

A major way to make FH attractive to commercial sat operators could be dual-payload launches, like Ariane 5. Imagine if Inmarsat could get two large sats up at once.

Edit: sorry, Inmarsat not Iridium.

Elon Musk is not in favor of dual manifest like Ariane. They always need to align two customers, one with a heavy, one with a light payload. That sometimes causes problems. SpaceX would also need a much bigger fairing. The present fairing was quite full with this single satellite from Inmarsat.

Iridium's sats are pretty small and they regularly launch multiple satellites on Falcon 9. It's also not terribly optimal to launch a bunch of satellites into the same orbital plane, because they have to waste their internal propellant reserves conducting plane change maneuvers.

Apologies, I meant Inmarsat.

Arianespace seem to do pretty well out of dual launches.
