This system has created the need of calling professionals from other countries. This is not literal but the general idea, hope its clear enough. Take care, Alejo. REF.: I'm a Spanish Teacher

The structure of the sentence is fairly strange. What I understand is something like: it's a system that has now led us to having to bring in professionals.

llevar = to take. lleva ahora = takes/took until now. In actual translation: It took the system until now to have to bring in professionals.
