Cost of new A/C install

[S/V Reveille]

I have a question about installing A/C in a Cabo Rico 45. It has never had a/c... so this will be a complete install from scratch...16k and 18k btu units. 3 outlets starboard side, 2 outlets port side, pump, thruhull, strainer, ducting, outlets, grills, controllers, ... everything. Does anyone know about what I'm looking at as far as expected cost? The self contained units are approx $3000 each. With all other necessary components, plus labor... Looking for a general ballpark guess based on experience. Thanks!
