There are a lot of "Embarques puerta a puerta" in the tri-state. If you negotiate and get good prices they pick up and put it in your house in DR.
One of them in the Bronx is N&T Express Cargo 718-716-2582, you can call them. I think their main office is in Manhattan. You do not have to worry about aduane. This is what Dominicans are doing. Good luck.
