Moving to Santo Domingo, DR need a reliable moving company + info on customs rules/restrictions?

Live in Miami Beach now planning a move onto Santo Domingo, DR... I have searched but have heard so many horror stories about moving companies + also heard plenty that the governement (customs) will allow or not into the country, + charges and other regulations... Does anyone know of a reputable & reliable moving company? also can you give me the dilly in regards to what I can move, whats the rules (i.e. cars? furniture: best to buy there or move it all?, etc)... Can someone put me in contact with folks whom can answer such questions??? THX :-D
