I do not know about any employment agencies in the DR
but if you are looking for a job you may try WWW.latpro.com
and click find a better job and then click latin america for the
region and then choose the Dominican Republic if you mark search
all key words you will have the entire small listing of some jobs in the Dominican Republic...you can also apply online too by just registering and they also send you updates on new jobs postings .Thanx for the idea about the need of a employment agency.... I see a nice opportunity here.
GOOD LUCK...Julio
