If they have ground staff at both ends one would think anything like car rentals and taxis would be organised in advance given they are touting a full service model.
It'll a difficult setup to get off the ground, but if they get traction and the regulator doesn't start raining on their parade they may well have a viable business provided it is managed properly. (Unfortunately being a pilot does not automatically make you a good candidate to run an aviation business)
The world of business is full of stories of people doing things that others said wouldn't work and making a success of it.
I wish them the best of luck in their venture
