Heading to Indonesia for 10 days during my Easter break. Looking for advice if anyones been before.

Flying into Bali but don't plan on spending too much of the time there, maybe 2/3 days. The main aim is to see Flores, Komodo etc. The main suggestion online seems to be to fly into one of the Flores airports, get a car and driver to travel across the island stopping along the way and then fly back to Bali from the other airport.

Has anyone done this, or similar? Any ideas of the cost of the car and driver etc?

Thanks
