Your question is very unclear.
I guess you could take a moto from 27 de Febrero, Santo Domingo to SDQ for a few hundred Pesos, send your luggage ahead by FedEx like Omega does, instead of carrying it.
Called Apolo Taxi (809 537-0000), the largest radio taxi service, and they say from Caribe Tours terminal at 27 de Febrero to Las Americas is RD$1,300. If you have a cell phone, you can call for a vehicle once you get in. The price should be similar at other radio services -- RD$1,600 is usually for an airport taxi to Santo Domingo.
If you are taking a taxi from Santo Domingo, with luggage and a number of people there is no way it will be as cheap as $40usd.
From the bus stop at the corner of the Samana Highway and the auto route to the airport it is almost that amount and this bus stop is only 15 minutes from the airport. You might almost be better off to rent a vehicle and drop it off at the airport. It might end up costing you the same or less.
