We need 3 wooden telephone/power poles

We are helping with the remodeling of the Centro Mutualista in La Romana- a non-profit clinic and vocational complex. We need to purchase 3 wooden telephone/power poles. When we lived in Santiago I could always get them at the Ochoa lumber yard on the road to Navarrette- does anyone know where I can find them in Santo Domingo or San Pedro or even Higuey?

Thanks for any help!
