It is all about interviewing locals. Since our experience suggests that female interpreters usually go better with interviewees we are looking for native Dominican female interpreter. So fare we are looking for 2-3 hours interpretation 2-3 times a week.I think it might be useful if you gave more information ... what type of interpreting? What do you mean by "advanced" ... legal, technical, commercial, negotiating, is advise on local products and services desired? Will it be at a set location, or would she be travelling with you? Approximately how many hours per day/week? Potentially developing into more or less hours? Why did you specify female?
