My wife organized twice, for a birthday party and a party on New Years eve,
a 7 person group from Casa del Son in Villa Mella.
We live in Naco, they came the day before to see the location and to know what cables they need.
On the day of the event they arrived 3 hours ahead, brought their sound equipment, installed everything and played Son, Salsa and Merengue at its best from midnight to 4 a.m.
The age of the players range between 30 and 70 years.
Twice we had great evenings.
The price should be negotiated by a Dominican National personaly.
For our last event 2005 we paid 15.000 RD$.
All the best.
